Mass converter

milligram to nanogram

Convert milligram (mg) to nanogram (ng). Use an editable mass converter, conversion formula, and reference table.

1,000,000

1 mg = 1,000,000 ng

Calculated in your browser

Conversion formula

ng = mg × 1,000,000

One milligram equals 1,000,000 nanogram. Multiply your value in milligram by this factor to get nanogram. For the reverse conversion, divide by the same factor.

Worked example

To convert 5 milligram:
5 × 1,000,000 = 5,000,000 ng

About these measurements

Mass quantifies an amount of matter.

The base reference used here is the gram. One milligram is 0.001 base units; one nanogram is 1e-9 base units.

Important distinctions

Mass is not force. Avoirdupois ounces and troy ounces have different masses.

Precision

The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.

Common questions

How do I convert mg to ng?

Multiply the quantity in mg by 1,000,000. You can also type the value into the converter above.

Can I reverse the conversion?

Yes. Use the swap button or open the nanogram to milligram converter.
