 # What is metric units with examples.

The metric system is defined as the system of measurements to calculate the mass, distance, and volume of any object. We generally use the metric system to measure smaller or larger quantities. The metric system of measurement in mathematics is the set of standard units defined to measure length, weight, and capacity. We follow the International System of Units (SI units).

### Units in metric system

The metric system is a system of measurement that uses the meter, litre, and gram as base units of length (distance), capacity (volume), and weight (mass) respectively. To measure smaller or larger quantities, we use units derived from the metric units.  The metric system consists of a set of units for measuring length, weight, capacity, temperature, etc.

• The standard unit used for measurement of length is meter.
• The standard unit used for the measurement of weight is a kilogram.
• The standard unit used for measurement of capacity is the litre.
• The standard unit used for time is seconds.

### What is meant by metric number prefixes?

The metric number prefix is defined as a unit prefix, which precedes a base unit to indicate the multiple or the submultiple of a unit. Some of the metric prefixes are:

• Kilo (1000 or 103)
• Hecto (100 or 102)
• Deca (10 or 101)
• Base unit (1)
• Deci (1/10 or 10-1)
• Centi (1/100 or 10-2)
• Milli (1/1000 or 10-3) (4) (1)
