Enter the total weight and the part weight in grams into the calculator to determine the percentage of the part weight relative to the total weight.

Grams to Percentage Formula

The following formula is used to calculate the percentage of a part weight relative to the total weight.

P = (PW / TW) * 100

Variables:

  • % is the percentage of the part weight relative to the total weight
  • PW is the part weight in grams
  • TW is the total weight in grams

To calculate the percentage, divide the part weight by the total weight and then multiply by 100 to convert it to a percentage.

What is Grams to Percentage Conversion?

Grams to percentage conversion is a way to express the weight of a part of a substance as a percentage of the total weight of the substance. This is commonly used in cooking, chemistry, and other fields where precise measurements are important. It helps in understanding the proportion of ingredients or components in a mixture.

How to Calculate Percentage from Grams?

The following steps outline how to calculate the percentage from grams.


  1. First, determine the total weight (TW) of the substance in grams.
  2. Next, determine the part weight (PW) of the substance in grams.
  3. Next, gather the formula from above = % = (PW / TW) * 100.
  4. Finally, calculate the percentage (%) of the part weight relative to the total 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 Weight (TW) = 200 grams

Part Weight (PW) = 50 grams
