**Definitions:**

**Kilogram** (abbreviations: **kg, or kgm**): is a SI (metric) system unit of mass (IPK, also known as "Le Grand K" or "Big K") and equivalent to 1/1000 of one gram. Where, at the temperature of melting ice, one gram is the absolute weight of a volume equal to the hundredth part of a metre cube of pure water.

**Newton** (abbreviation: **N**): is the International System of Units (SI) derived unit of force. It is named after Isaac Newton in recognition of his work on classical mechanics, specifically Newton's second law of motion. One newton is the force needed to accelerate one kilogram of mass at the rate of one metre per second squared in direction of the applied force.

## How to Convert Kilograms to Newtons

*Example: How many newtons are equivalent to 3.13 kilograms?*

As;

1 kilograms = 9.80665 newtons

3.13 kilograms = Y newtons

Assuming Y is the answer, and by criss-cross principle;

Y equals 3.13 times 9.80665 over 1

(i.e.) Y = 3.13 * 9.80665 / 1 = 30.6948145 newtons

Answer is: 30.6948145 newtons are equivalent to 3.13 kilograms.
