Convert Atomic mass unit to gram
Please provide values below to convert Atomic mass unit [u] to gram [g], or Convert gram to Atomic mass unit.
1 u = 1.6605e-24 g. To convert Atomic mass unit to gram, multiply the value by 1.6605e-24; to go the other way, divide by it (1 g = 6.0221e+23 u). Both units measure weight and mass and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 u = 1.6605e-24 g
- 1 g = 6.0221e+23 u
- 10 u = 1.6605e-23 g
- 100 u = 1.6605e-22 g
How to Convert Atomic Mass Unit to Gram
1 u = 1.6605390666e-24 g
Example: convert 15 u to g:
15 u = 15 × 1.6605390666e-24 g = 2.4908085999e-23 g

Atomic Mass Unit
The atomic mass unit (u) is a standard unit of mass used to express atomic and molecular weights, defined as one twelfth of the mass of a carbon-12 atom.
History/Origin
The atomic mass unit was introduced in the early 20th century to provide a convenient scale for atomic weights. It was originally based on the mass of hydrogen but was later standardized to be one twelfth of the mass of a carbon-12 atom, which was adopted as a reference in 1961 by the IUPAC.
Current Use
The atomic mass unit is widely used in chemistry and physics to express atomic and molecular masses, facilitating calculations in molecular chemistry, nuclear physics, and related fields.
Gram
The gram (g) is a metric unit of mass equal to one thousandth of a kilogram.
History/Origin
The gram was originally defined in 1795 as the mass of one cubic centimeter of water at its maximum density. It became part of the metric system established in France and was later standardized as part of the International System of Units (SI) in 1960.
Current Use
The gram is widely used worldwide for measuring small masses in everyday life, science, and industry, especially in contexts like food labeling, pharmaceuticals, and laboratory measurements.
