Definition of Kilogram

Definition
The kilogram (kg) is the SI base unit of mass. Since 2019, it is defined by fixing the numerical value of the Planck constant, ensuring stability independent of physical artifacts.

The kilogram is universally used in science, engineering, medicine, commerce, and daily life, forming the reference point for all metric and many non-metric mass units.
Exact factor
Base unit: 1 kg = 1000 g = 2.2046226218 lb
Examples
• 70 kg ≈ 154.32 lb
• 80 kg ≈ 12 st 8.37 lb

About the Kilogram

Facts & Uses

  • SI base unit of mass — the only base unit redefined in 2019 (26th CGPM) by fixing the Planck constant at exactly 6.62607015 × 10⁻³⁴ J·s, replacing the 130-year-old physical artifact.
  • Universal reference for science, medicine (drug dosage, body weight), commerce (food, freight), and engineering (mechanical loads, structural design).
  • Used in nutrition labels, fitness (BMI, weight loss), and international shipping where customs declarations require metric mass.
  • Subdivisions: gram (cooking, lab), milligram (pharmacy, dosing), microgram (toxicology); multiples: tonne (industry, freight).

Curiosities

  • Until 20 May 2019, the kilogram was defined as the mass of the International Prototype Kilogram (IPK), a platinum-iridium cylinder kept in a vault near Paris since 1889.
  • Comparisons with sister copies showed the IPK was drifting by ~50 µg per century — enough to motivate the redefinition via a fundamental constant.
  • The kilogram is the only SI base unit whose name still contains a metric prefix ("kilo"), a historical quirk inherited from the 1795 French metric system.
  • Approximate equivalents: 1 kg ≈ 2.2046 lb ≈ 35.274 oz ≈ 0.157 stone.

Frequently Asked Questions

How many kilograms are in one kilogram?

One kilogram equals 1 kilograms. To convert, multiply the kilogram value by 1. For the reverse, divide the kilogram value by 1 (or multiply by 1).

What is 0.1 kilograms in kilograms?

0.1 kilograms = 0.1 kilograms. This is one of the most commonly searched conversions for this pair.

How precise is the kilogram-to-kilogram conversion?

The factor 1 is accurate to 6 significant figures, derived from international measurement standards. Our calculator uses full precision internally.
