Unit Definitions

Meter (m)

A meter is the base unit of length in the International System of Units (SI). It is defined as the distance light travels in a vacuum in 1/299,792,458 of a second. It is used worldwide for length measurements.

1 meter = 100 centimeters = 1000 millimeters = 10 decimeters = 0.001 kilometers = 3.28084 feet = 39.3701 inches

Millimeter (mm)

A millimeter is a metric unit of length equal to one-thousandth of a meter (1/1000 m). It is the smallest common metric unit for length measurements and is widely used in engineering, manufacturing, and precision measurements.

1 millimeter = 0.1 centimeters = 0.01 decimeters = 0.001 meters = 0.000001 kilometers = 0.0393701 inches

Common Use Cases

  • Engineering and construction specs.
  • Manufacturing tolerances.
  • Science lab measurements.
  • Metric prefix homework.
