SI - Measuring Distance

Measuring intervals of distance and length is relatively straightforward. Fractions of meters are typically measured using the standard prefixes associated with the (decimal) metric system.

Fractions of Meters:
Prefix Abbrev. Decimal Form Exponent
meters m. 1. 100
millimeters mm. .001 10-3
micrometers µm. .0000001 10-6
nanometers nm. .000000001 10-9
picometers pm. .000000000001 10-12

Multiples of meters adhere to the same standards laid out within the metric system as the fractional measurements.

Multiples of Meters:
Prefix Abbrev. Decimal Form Exponent
meters m. 1. 100
dekameter dam. 10. 101
hectometer hm. 100. 102
kilometer km. 1000. 103

The meter is the standard measure of length and distance within the metric system.
