The metric system uses base units, which are units that are chosen as a measurement of a base quantity such as length, weight/mass, volume/capacity, and more. Below are some of the base units in older versions (not SI) of the metric system: Length: meter (m) Weight: gram (g)
- Length - meter (m)
- Time - second (s)
- Amount of substance - mole (mole)
- Electric current - ampere (A)
- Temperature - kelvin (K)
- Luminous intensity - candela (cd)
- Mass - kilogram (kg)

What is the base number of the metric system?
The metric system is a base 10 system. This means that each successive unit is 10 times larger than the previous one. The names of metric units are formed by adding a prefix to the basic unit of measurement. To tell how large or small a unit is, you look at the prefix. To tell whether the unit is measuring length, mass, or volume, you look at the base.

Base units include the kilogram, meter, and liter (liter is a derived unit). Prefixes include milli-, centi-, deci-, and kilo. The temperature scale used in the metric system is the Kelvin scale or Celsius scale, but prefixes are not applied to degrees of temperature.
What is the metric system?
Updated November 25, 2019. The metric system is a decimal-based system of measurement originally based on the meter and kilogram, which were introduced by France in 1799. "Decimal-based" means all the units are based on powers of 10. There are the base units and then a system of prefixes, which may be used to change the base unit by factors of 10.
What are the basic units of measure?
The kilogram, meter, and second are the fundamental base units upon which the metric system is built, but seven units of measure are defined from which all the other units are derived: 1 Kilogram: The kilogram (kg) is the base unit of mass. 2 Meter or Metre: The meter (m) is the unit of length or distance. 3 Second: The second (s) is the fundamental unit of time. 4 Kelvin : The Kelvin (K) is the metric unit of temperature. 5 Mole : The mole (mol) is a unit for a quantity of a substance. 6 Ampere: The Ampere (A) is the unit of electric current. 7 Candela: The candela (cd) is the unit of luminous intensity. The candela is sometimes called by its old name, the candle.

The liter or litre (L) is an SI derived unit of volume, equal to 1 cubic decimeter (1 dm 3) or 1000 cubic centimeters (1000 cm 3 ). The liter actually was a base unit in the original French metric system but is now defined in relation to length.
How to convert between units?
Converting Between Metric Units. In order to convert between units, it's only necessary to multiply or divide by powers of 10. For example, 1 meter is 100 centimeters (multiply by 10 2 or 100) and 1000 milliliters is 1 liter (divide by 10 3 or 1000). Helmenstine, Anne Marie, Ph.D.

What is the metric system of measurement?
The metric system of measurement is the standard way of measuring distance, calculating height, and most of the other day-to-day items. For instance, let's consider a jar of milk. We use liters to find the volume of milk and meters (or centimeters) to find the height of the jar. This is because these metric units are followed in most places worldwide and are called SI units (International System of Units). Let's begin and learn more about the metric system.

The standard unit for measurement of weight is a kilogram. The standard tool we use to measure weight is the beam-balance or the weighing scale. These are some examples that show where the weight measurements are typically used:
The International System of Units (SI)
Officially known as the International System of Units (SI), the metric system is the international standard system of measurement. It is based on the standard decimal number system, and is designed to be easy to learn, and simple to use.
Everyday units
The simplicity and logic of the metric system has led it to become the universal measurement system for everyday use all over the world. Factors contributing to its success include:
Weight
When the word “weight” is used, the intended meaning should be clear. In science and technology, weight is a force, for which the SI unit is the newton. However, in commerce and everyday use, weight is usually a synonym for mass, for which the SI unit is the kilogram.
Temperature
The degree Celsius, symbol °C, is the special name for the kelvin. For everyday use, the degree Celsius is the standard unit used to measure temperature.
Force
One newton is equal to the force needed to accelerate a mass of one kilogram at the rate of one metre per second squared in the direction of the applied force.
Pressure
One pascal is equal to the pressure exerted by a perpendicular force of one newton on an area of one square metre.
Energy
The SI unit of energy is the joule, symbol J. It is used to measure energy in all its forms; potential, kinetic, mechanical, electrical, chemical, heat, etc.

What does the prefix "deci" mean in metric?
Ans: In the metric system of measurement, multiple designations and subdivisions of any unit can be accomplished by combining the prefixes such as "deka, hecto, and kilo," meaning 10, 100, and 1,000, and “deci, centi, and milli,” meaning 1/10th, 1/100th, and 1/1000th respectively, with the name of the unit.

In 1,790, the French National Assembly commissioned the Academy of Sciences to develop a new decimal system of units; the system they developed is considered as the metric system .
