What are the possible units for measuring length or distance in the metric system?

Answer 1

Metre(m) is the fundamental unit. You can prefix centi-, kilo-, milli-, nano- etc to it to get bigger and smaller units. For example, 1000 meters is a kilometre(km) and 1/1000th of a metre is a millimetre(mm). Prefixes:
* p (pico) 10-12 * n (nano) 10-9 * µ (micro) 10-6 * m (milli) 10-3 * k (kilo) 103 * M (mega) 106 * G (Giga) 109 * T (Tera) 1012 In addition to the above, 10 mm make a centimetre(cm).

Answer 2

Meter is the basic unit, then we have derivations: millimeter (one thousand times smaller part), centimeter (one hundred times smaller), decimeter (one tenth of a meter), kilometer (one thousand meters), but there are also pico-, nano-, micro-, mega-, giga-, peta-, exa-, etc. but these are not used so often.

Answer 3

The base unit for length is the meter. In theory, you can combine that with any SI prefix (check the Wikipedia for "SI prefixes" for the full list); but in practice, units larger than "kilo" (kilometer) are seldom used.

Answer 4

The metric system uses units such as meters (m), centimeters (cm), millimeters (mm), kilometers (km), and micrometers (µm) to measure length or distance. These units are based on powers of ten, making conversions between them straightforward.

Answer 5

meter, kilometer, centimeter, decimeter, millimeter, nanometer...
