How the Conversion Works

This calculator uses a two-step conversion process through kilograms (kg) as the base unit, which is the standard unit of mass in the International System of Units (SI).

Conversion Formula:

Step 1: Convert from mg to kilograms (kg)

Value in kg = Input value ÷ 1,000,000

Step 2: Convert from kilograms (kg) to µg

Result = Value in kg × 1,000,000,000

Simplified Formula:

Result = Input × 1000
Where 1000 is the conversion factor from mg to µg

Example Calculation:

Let's convert 16 mg to µg:

16 mg ÷ 1,000,000 = 1.600e-5 kg
1.600e-5 kg × 1,000,000,000 = 16,000 µg

Result: 16 mg = 16,000 µg
