How to convert Atomic Mass Units to Grams
Multiply the atomic mass units value by 1.6605e-24: 1 u = 1.6605e-24 g. Going the other way, 1 g = 6.0221e+23 u, so divide by 1.6605e-24 or use the Grams to Atomic Mass Units converter.
About these units
Atomic Mass Units (u)
An atomic mass unit is one twelfth of the mass of a carbon-12 atom, about 1.6605 × 10⁻²⁷ kilograms. Atomic and molecular masses are expressed in this unit.
Grams (g)
A gram is one thousandth of a kilogram, roughly the mass of a paperclip. Recipes, nutrition labels and postage are commonly measured in grams.
