Conversion of Milligrams to Grains (mg to g): An Ultimate Guide

Understanding the Conversion

The conversion between milligrams (mg) and grains (g) is essential in various fields, including medicine, cooking, and scientific research. A milligram is a metric unit of mass equal to one-thousandth of a gram, while a grain is a traditional unit of mass in the imperial system.

Formula for Conversion

The formula for converting mg to g is:

g = mg / 1000

For example, to convert 500 mg to g:

g = 500 mg / 1000 = 0.5 g
