Why the kilogram-to-gram conversion factor holds

The conversion factor between kilograms (kg) and grams (g) is based on the metric system's definition of a kilogram as 1,000 grams.

Definition

A kilogram is the base unit of mass in the metric system, and a gram is a subunit defined as one-thousandth of a kilogram.

Principle

The conversion works by applying the fixed relationship between the units: 1 kg equals 1,000 g, and 1 g equals 0.001 kg.

Assumptions

  • The metric system definition is used, where 1 kg is defined as exactly 1,000 g.
  • The conversion factor is exact and not subject to measurement uncertainty.

Cautions

  • Round the result to the precision required by your calculation.
  • Do not use this conversion for any units not defined by the metric system.
