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.
