# What is the definition of the SI standard units?

Among numerous conventional units, there are some that are called the standard unit because they are not derived from any other unit; these are:

**Metro** – Unit of length;

**Second** – Unit of time;

**Kilogram** – Unit of mass;

**Ampère** – Electric current unit;

**Kelvin** – Temperature unit;

**Mol** – Unit of quantification of matter;

**Candela** – Unit of luminous intensity.

As they are not derived from any other unit, they are standardized through measures that may seem somewhat curious, as you can see below:

**What is metro?**

The meter is defined as the length of the path traveled by light in a vacuum, over a time interval of 1 / 299,792,458 seconds.

**What is second?**

The second is defined as the duration of 9 192 631 770 periods of radiation corresponding to the transition between two hyperfine levels of the ground state of the cesium atom 133.

**What is kilogram?**

The kilogram is defined on the basis of a standard unit, which has been stored in the International Office of Weights and Measures, in Sèvres, France, since 1889. This standard unit is an equilateral cylinder 39 mm high by 39 mm in diameter , composed of Iridium and Platinum.

**What is an amp?**

The ampere is defined as the current that produces an attractive

**What is kelvin?**

Kelvin is defined as the fraction 1 / 273.16 of the thermodynamic temperature of the triple point of water.

**What is mol?**

The mol is the amount of matter in a system that contains as many elementary entities as there are atoms contained in 0.012 kilograms of carbon-12.

**What is candela?**

The candela is defined as the luminous intensity emitted by a source, in a given direction, of monochromatic light of frequency 540 x 1012 Hertz, and whose radiation intensity in such direction is 1/683 watts per sphere.
