**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.

**Kilonewton** (abbreviation: **kN**): is the International System of Units (SI) derived unit of force where 1 kN = 1000 N. It is named after Isaac Newton in recognition of his work on classical mechanics, specifically Newton's second law of motion.

## How to Convert Kilograms to Kilonewton

*Example: How many kilonewton are equivalent to 27.21 kilograms?*

As;

1 kilograms = 0.0098066358553261 kilonewton

27.21 kilograms = Y kilonewton

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

Y equals 27.21 times 0.0098066358553261 over 1

(i.e.) Y = 27.21 * 0.0098066358553261 / 1 = 0.26683856162342 kilonewton

Answer is: 0.26683856162342 kilonewton are equivalent to 27.21 kilograms.
