Enter the total ring weight (g) and the gold purity percentage (%) into the Gold Ring Weight Calculator. The calculator will evaluate the Gold Ring Weight. 

Gold Ring Weight Formula

The following two example problems outline the steps and information needed to calculate the Gold Ring Weight.

GRW = RW * P / 100


  • GRW is the Gold Ring Weight (g)
  • RW is the total ring weight (g) 
  • P is the gold purity percentage (%) 

To calculate the gold ring weight, multiply the total ring weight by the purity percentage, then divide by 100.

How to Calculate Gold Ring Weight?

The following steps outline how to calculate the Gold Ring Weight.

  1. First, determine the total ring weight (g). 
  2. Next, determine the gold purity percentage (%). 
  3. Next, gather the formula from above = GRW = RW * P / 100.
  4. Finally, calculate the Gold Ring Weight.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total ring weight (g) = 45

gold purity percentage (%) = 50

GRW = RW * P / 100 = ?
