Length Area Volume

The meter (m) is the SI unit of length. Other units of length have also been used. Examples:

1 angstrom (A) = 10-10m = 0.1 nm 1 micron (= 10-6 m = 1 ^m 1 millimicron (m^) = 10-9 m = 1 nm

American and British units of length: 1 inch = 0.0254m = 25.4mm 1 foot = 0.3048 m 1 yard = 3 feet = 0.9144 m 1 (statute) mile = 1609.344 m ยป 1.61 km 1 nautical mile = 1.853 km

The square meter (m2) is the derived SI unit of area, and the cubic meter (m3) is the corresponding unit of volume. When denoting the fractions or multiples of these units with prefixes (Table 2), please note that there are some peculiarities. Examples: 1 m = 103 mm, but 1 mm2 = 106mm2, and 1 m3 = 109mm3

The liter (L or l)* is often used as a unit of volume for liquids and gases: 1 L = 10-3 m3 = 1 dm3 1mL= 10-6m3 = 1 cm3 1 ^L= 10-9m3 = 1 mm3.
