# What is the smallest unit of measurement in the metric system?

**Solution:**

The most basic unit of length is meter.

What is a metric system?

The metric system is a system of measurement that makes use of meter, liter, and gram as base units of length (distance), capacity (volume), and weight (mass) respectively. The metric system has its beginnings back in 1670 by a mathematician called Gabriel Mouton.

The smallest unit, as the above diagram clearly suggests, is the millimeter.

1 millimeter = 10^{-3} meters

1 millimeter = 10^{-1}centimeter

1 millimeter = 10^{-6} kilometer

The metric system is an alternative system of measurement used in most countries, as well as in the United States. The metric system is based on joining one of a series of prefixes, including kilo-, hecto-, deka-, deci-, centi-, and milli-, with a base unit of measurements, such as meter, liter, or gram. Units in the metric system are all related by a power of 10, which means that each successive unit is 10 times larger than the previous one. This makes converting one metric measurement to another a straightforward process and is often as simple as moving a decimal point. It is always important, though, to consider the direction of the conversion. If you are converting a smaller unit to a larger unit, then the decimal point has to move to the left (making your number smaller); if you are converting a larger unit to a smaller unit, then the decimal point has to move to the right (making your number larger).

Therefore, the smallest unit for length measurement in the metric system is the millimeter.

**Summary:**

The smallest unit for length measurement in the metric system is the millimeter.
