Kilograms (kg) and micrograms (μg or mcg) are both units of mass, but sometimes you need to convert between them. Whether it’s for cooking or chemistry, accurate conversions from kilograms to micrograms matter. This article explains how.
Kilograms and micrograms
A kilogram (kg) is the base unit of mass in the metric system. A microgram (μg or mcg) is a tiny unit of mass equal to one millionth of a gram.
To give you an idea of the difference, here’s the conversion factor:
1 kg = 1,000,000,000 μg (or 1e+9 μg)
Kilograms to Micrograms Conversion Formula
Here’s the formula you’ll need:
m(μg) = m(kg) × 1,000,000,000
To convert kilograms to micrograms, multiply the kilogram value by 1,000,000,000.
For example, if you want to convert 2 kg to micrograms: 2 kg 1,000,000,000 = 2,000,000,000 μg.
