Meters and centimeters will almost always have a number next to the mark; all you have to do is write that number down along with the unit of measure. Millimeter marks usually are not numbered, but because there are only 10 millimeters between each centimeter, they're easy to count. Make ...
If you want to measure how long an object is, you might measure it using inches, centimeters, feet, millimeters or yards. All of these are units that we use to measure length. Answer and Explanation: To convert centimeters to inches, you need to know how centimeters and inches compare to...
How do you measure the power of a lens?If you've ever looked through binoculars, a telescope, or a magnifying glass, you'll know that some lenses magnify (or reduce) the apparent size of an object much more than others. There's a simple measurement that tells you how powerful a lens...
Take note of millimeters as well as centimeters for more accurate measurements. For example, if the part of the shape you measure is slightly longer than 20 cm, count the number of small millimeter marks between the 20 and 21 cm marks on the ruler. If you count four marks, the precise ...
Scientists employ tide gauges and satellites to measure sea level, using long-term data to account for the natural fluctuations and achieve a more accurate average. The general scientific consensus indicates that oceans are rising approximately 2 millimeters per year. An accurate measurement of sea le...
Lens width is the width of one of your lenses in millimeters, from one side to the other. You might hear this called eye size. This is the most important measurement to make sure your frames fit your eyes. When measuring this with a metric tape measure, make sure you just measure the...
How do I know my pupillary distance? Two ways: You can measure it using our special ruler You can obtain it from your optometrist You may not have realized, but each time you purchased glasses from an optometrist, they measured and used your PD to craft your lenses. Unfortunately, this...
The standard unit used for distance in scientific disciplines is the meter. Often, however, it doesn't make sense to physically measure distances in meters. A real long distance may be measured by a person in kilometers, and a real short distance could be measured in millimeters or centimeter...
Parkinson:There's all kinds of them. I knew we could position to a meter or two, and I knew there was a technique to get down to millimeters, but it involves a signal processing technique that I didn't think was robust. Engineers proved me wrong. If you can do that, you can use ...
