Enter the volume measured density and the number of grains into the calculator to determine the number of cubic centimeters (CCs).

Grain To CC Formula

The following equation is used to calculate the number of cubic centimeters from grains.

CC = gr * VMD

  • Where CC is the cubic centimeter (CC)
  • gr is the grains
  • VMD is the volume measured density

What is a grain?


A grain is a unit of weight equal to .065 grams.

How to Calculate Grain To CC?

Example Problem:

The following example outlines the steps and information needed to calculate cc from grains.

First, determine the number of grains. In this example, the number of grains is 40.

Next, determine the volume measured density. In this example, this is determined to be .06479791.

Finally, calculate the CC from grains using the formula above:

CC = gr * VMD

CC = 40 * .06479791

CC = 2.591 cm^3
