About Converting Nanograms to Femtograms
Weight conversions between Nanogram and Femtogram come up constantly in everyday commerce, shipping, and cooking, since US packaging is usually labeled in pounds while most of the rest of the world uses kilograms. Specifically: Nanogram is 1e-9 gram units, and femtogram is 1e-15 gram units.
Formula
femtograms = nanograms × 1000000
This factor comes from each unit's defined relationship to the category's base unit: 1 nanogram equals 1e-12 base units, and 1 femtogram equals 1e-18 base units, so dividing one by the other gives the direct nanogram-to-femtogram factor of 1000000.
Simple example
1 ng × 1000000 = 1,000,000 fg
1 nanogram = 1,000,000 femtograms.
Real-world example
50 ng × 1000000 = 50,000,000 fg
50 nanograms = 50,000,000 femtograms.
