Meter Prefixes and Other Units

This section introduces prefixes used on 'meter' to represent decadic multiples or fractions of a meter. It also covers other standard units to measure distances like foot, mile, nautical mile and lightyear.

For the convenience of measuring a very long or very short distance, some prefixes have been defined on "meter" to be decadic multiples or fractions of a meter. Here are some commonly used meter prefixes and their abbreviated symbols:

Prefix   Name         Symbol   Definition

peta     petameter    Pm       1 000 000 000 000 000 meters
tera     terameter    Tm       1 000 000 000 000 meters
giga     gigameter    Gm       1 000 000 000 meters
mega     megameter    Mm       1 000 000 meters
kilo     kilometer    km       1 000 meters
         meter        m        1 meter
deci     decimeter    dm       0.1 meter
centi    centimeter   cm       0.01 meter
milli    millimeter   mm       0.001 meter
nano     nanometer    nm       0.000 000 001 meter

femto    femtometer   fm       0.000 000 000 000 001 meter

Beside "meter", other standard units are also used to measure distances. For example:
