Either one is fine. But depending on what you're measuring, one of them will give you
a convenient number, and the other one will give you an awkward number.
Examples:
The length of a small paperclip: 30 millimeters, 0.000003 kilometer
The length of a major city block: 1,609,344 millimeters, 1.61 kilometers
to get the precise measurment of a line to the nearest milimeter you have to divide 5/6*15-7 when you solve that you answer should be 20.3 and then multiply 45 and your answer should be 193.3if you have any questions about this problem email me at : justinb2@gmx.com Thank You
This should not be taken as a precise measurement of 1 mm, but this hypen: - is approximately a millimeter in length. It's the closest I can do on the keyboard.
you measure the thickness of a book in inches.
There are 2.54 centimeters in one inch. So take your measurement in inches and multiply it by 2.54 to change the unit to centimeters. In this case, the answer is 109.22 centimeters. Algebraic Steps / Dimensional Analysis Formula 43 in* 2.54 cm 1 in = 109.22 cm
If by mm2, you mean mm2. Then it means square millimeter - a measurement of area being one millimeter by one millimeter. It is equal in size to 0.01 cm2 (1 mm = 0.1 cm and 0.1 x 0.1 cm = 0.01 cm2).
miles
miles Distances between cities should be measured in either miles or kilometers.
measure you should probably put down is kilometers
It would be more appropriate to measure a book in centimeters as meters might be too large a unit of measurement for a book. Additionally, centimeters provide a more precise measurement for the size of a book.
You could measure the length or width of it but you would have a decimal. You should be using centimeters.
You're fine don't worry.
Perimeter is typically measured in linear units, such as meters, centimeters, feet, or inches, depending on the context. It represents the total distance around a two-dimensional shape. For larger areas, it may also be expressed in kilometers or miles. The choice of unit should be consistent with the measurement of the shape's dimensions.
centimeters or cm in the metric system or SI and in the customary inches or in.
milimeter or money market Should be millimetre (or millimeter).
Liter is a specific unit; the question should be, "metric units for volume". Volume is measured in cubic meters; for larger volumes you might use square kilometers; for smaller volumes, such as those that occur in everyday situations, you would usually use cubic decimeters (= liters), cubic centimeters (= milliliters), or cubic millimeters.
centimeters
This distance is 20 000 000 cm.
