Why the conversion factor between milligram and kilogram holds
The conversion factor of 0.000001 holds because both the milligram (mg) and the kilogram (kg) are defined in terms of the kilogram, which is the base unit of mass in the metric system.
Definition
The milligram (mg) is a unit of mass equal to 0.000001 of a kilogram. The kilogram (kg) is the base unit of mass, defined as 1 kg.
Principle
To convert from mg to kg, you multiply the mass in mg by the factor that expresses how many kg are in one mg. The factor 0.000001 is derived directly from the definition: 1 mg = 0.000001 kg. Multiplying by this factor scales the value from the smaller unit to the larger base unit.
Assumptions
- The conversion uses the standard metric definitions where 1 mg is exactly 0.000001 kg.
Cautions
- When performing calculations, round the result to the precision required for your specific application.
