Enter the total mass in grams (g) into the Atomic Mass Units Calculator. The calculator will evaluate and display the equivalent Atomic Mass Units. 

Atomic Mass Units Formula

The following formula is used to calculate the Atomic Mass Units. 

AMU = #g * 6.0229552894e+23

  • Where AMU is the Atomic Mass Units (atomic mass units)
  • #g is the total mass in grams (g) 

How to Calculate Atomic Mass Units?

The following example problems outline how to calculate Atomic Mass Units.

Example Problem #1:

  1. First, determine the total mass in grams (g). 
    • The total mass in grams (g) is given as: 5.
  2. Finally, calculate the Atomic Mass Units using the equation above: 

AMU = #g * 6.0229552894e+23

The values given above are inserted into the equation below and the solution is calculated:

AMU = 5* 6.0229552894e+23 = 3.0114 e+24 (atomic mass units)


Example Problem #2: 

For this problem, the variables needed are provided below:

total mass in grams (g) = 8

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer. 

AMU = #g * 6.0229552894e+23 = ?
