What Does MM Mean On A Lens? + Which Lens To Choose

The 44mm Apple Watch SE, Apple Watch Series 4, Apple Watch Series 5, and Apple Watch Series 6 have a slightly bigger battery than the 40mm watch due to more room in the casing. If battery life is most important to you, this is something to consider. It literally means that the water depth will be 0.5mm. For example, if you place a container under the rain and it fills up to 0.5mm, then the precipitation is 0.5mm. +1 This answer explains best why the area doesn’t matter, and shows that length is indeed a good measurement, which I think is the crux of the question.

• The various definitions, examples, and related terms listed above have been written and compiled by the Slang.net team.
• If you want the largest and clearest screen available on an Apple Watch, then the 44mm is the one for you.
• If you had a 10×10 meter empty pool before the rain, it would also fill up 3mm.

It makes the most sense considering that “million” starts with the letter “M.” Most abbreviations follow this standard practice. The Latin numeral MM is frequently used to designate that the units used in presenting information (financial and non-financial) are in millions. The example below shows how figures can be portrayed in millions.

Basically, this number tells you how zoomed in the lens is, to be straightforward about it. An acronym sometimes used on Twitter when referencing a song or music that you think others should listen to. To reach m from mm, we must jump three places to the left. So, we have to divide 750 by $(10 \times 10 10)$ or 1000. Territory includes Washington, Oregon, Montana, Idaho, Hawaii, Alaska, California, and Utah.

MM definition by Slang.net

People, pets, models, and fashion photographers often use a short telephoto lens. The functional distance between the front of the lens and its focal plane is how camera engineers tend to describe focal length. In everyday terms, the focal length number impacts how much you see and the angle of view when you look through the lens. For example, a focal length for a 16mm lens will show a much wider frame than that of a 200mm lens. “Millimeter” is a unit of length that equals one-thousandth of a meter.

Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Around here my mission is to help you improve your photography, photo editing, and graphic design through easy-to-understand tutorials that maximize your creativity. These lenses mimic the perspective the human eye sees the most, so they also tend to be very easy to use for brand-new photographers. Lenses are divided into six categories based on their focal lengths. Each of these MMs of the lens are best for certain types of subjects.

Most Common Mm Meaning

My impression was the OP needed a distinction between a drizzle and a light rain, inter alia. It holds whether the container is the size of a tennis court, or the size of a small beaker or a test tube with a flat bottom. For exactly the same reason, exposure in photography is the same regardless of sensor size. Connect and share knowledge within a single location that is structured and easy to search.

Total rainfall is still measured from 0900 to the next day at 0900. «1 liter per m²» is right, because that again is a unit of length. To calculate «how much rain fell on Hong Kong» , you’d take the area of Hong Kong, and multiply it by 1 mm. That’s usually not what people want to know, though — they want to know how wet things got, and the volume-per-area number is most convenient for that. It’s confusing to measure liquid in units of length instead of volume, isn’t it? Earth Science Stack Exchange is a question and answer site for those interested in the geology, meteorology, oceanography, and environmental sciences.

We have managed to find 300mm units of energy, which should be more than enough to get this experiment going. Harold Averkamp has worked as a university accounting instructor, accountant, and consultant for more than 25 years. He is the sole author of all the materials on AccountingCoach.com. The Structured Query Language comprises several different data types that allow it to store different types of information…

Assuming the cup has vertical sides, the https://1investing.in/ measurement would remain correct regardless of the size of cup you use. We have measures like meters and kilometers to express bigger distances, like the distance between two cities, the height of mountains, lengths of rivers, etc. However, the length of the wheat grain, the size of an ant, the thickness of a paper, etc., are some measures we find difficult to express in bigger units of measurement like meters.

Some people with small wrists will want the bigger watch and vice versa. Unlike the Watch’s two height options and two display densities, there’s no difference when it comes to the thickness of the Apple Watch 40mm vs. 44mm. This one goes up to 12 cm or 120 mm, so 3 mm would just be a few drops at the bottom. Simply, an «amount» of rain is a certain volume, and volume equals area x height. This is just a definition, which I already know (and in which I believe you missed that it’s per hour).

It means that during the rain event , one square meter of ground was filled with water up to a height of 3mm. @JanvanBloem the answer correctly measures total precipitation . If you are interested in precipitation rates (e.g. units of mm/hr), please edit your question to address this. And it’s still true that a storm that affects a larger area with 3mm of rainfall does put down more total water quantity in entirety.

This table provides a summary of the Length or Distance units within their respective measurement systems. These days I primarily focus my efforts on this site, creating guides and tutorials that I wish I had earlier in my career. Each week I publish new tutorials on Photography, Photoshop, Lightroom, and Canva to help you unlock new skills and bring your creativity to new levels! Everything you learn here is backed by real experience, so you can finally skip the fluff and focus only on what matters.

• This one goes up to 12 cm or 120 mm, so 3 mm would just be a few drops at the bottom.
• Making statements based on opinion; back them up with references or personal experience.
• The Greeks would refer to the god of the sea as Poseidon, whereas the Romans would call him Neptune.
• The beads, measuring less than a millimeter across, were found in soil samples collected by the Chinese Chang’e-5 mission.
• You might come across “mm” in scientific or engineering fields, where different values are required, and they can reach well into the millions as a unit.

This is an understandable thought process, considering longer lenses are much more expensive! However, the larger the MM does not mean the lens is better – lenses don’t really work that way. A millimeter is usually the smallest unit you can measure using a regular ruler.

Bring vs. Take Both words imply motion, but the difference may b… For reference, 5G’s millimeter-wave frequencies top out at 52.6 GHz. Dentists, meanwhile, can quantify the bone levels affected by gum disease down to the millimeter. Once a week, Young’s team at Scripps uses a truck — with an image scanner on top — to map the face of the cliffs down to the millimeter.

If the same storm hits all of China, that’s indeed a lot of water! But of course it’s also a larger area to absorb that water. So regardless of whether it’s a Hong-Kong sized downpour or a China sized rain system, if it puts down 3mm, it tends to have similar impacts throughout the region affected. Especially when you are just getting into photography, figuring out which lens to get is super overwhelming. The easiest way to choose the right focal length is to make sure it’s as versatile as possible.

However, there are many units smaller than a millimeter. The smallest unit of measuring length is Planck Length. We can use the following chart to find the approximate results for the conversion of customary units. In case you are wondering how to measure length in millimeters or how a length of a millimeter or 1 mm looks like, let’s check it out on a ruler. I know I have seen jobs posted that pay $50K, and K is meant to stand in for a thousand.

Most country’s weather services report the amount of rain over a day and add the amounts together to get monthly or annual measurements, but it is possible to take measurements more frequently. More frequent measurements can be used to report rainfall intensity over a shorter period. So you, for example, could report the maximum hourly rainfall intensity within a day. You can also use more frequent measurements to calculate how quickly streamflow responds to a rainstorm.

Ultra wide-angle lenses are the widest field of view you can get in an optic! Landscape, architecture, and real estate photographers love ultra-wide-angle lenses because of that sweeping field of view. Agents will also commonly see us communicate M as thousands when we quote surety rates or agent commissions. For example, the standard Class B rate starts at $25/M for the first $100M; then $15/M for the next $400M; then $10/M for the next $2MM. Those rates are expressed per thousand and the MM denotes millions.

Because of the longer outstanding checks, short telephoto lenses can be used for action photography and wildlife. However, other telephotos tend to be a more popular choice for these subjects. Standard lenses are popular as they are closest to the angle of view we humans see. These lenses have minimal distortion, which can be flattering to the subject. They tend to use large apertures and allow a lot of light to enter the lens which makes them fast in low light conditions. Large apertures (f/1.8 – f/1.4) also produce a pleasing out-of-focus effect to the background which concentrates the attention of the viewer on the subject.
