How to Convert Milligrams to Pounds

To convert a measurement in milligrams to a measurement in pounds, multiply the weight by the following conversion ratio: 2.2046E-6 pounds/milligram.

Since one milligram is equal to 2.2046E-6 pounds, you can use this simple formula to convert:

pounds = milligrams × 2.2046E-6

The weight in pounds is equal to the weight in milligrams multiplied by 2.2046E-6.

For example, here's how to convert 500,000 milligrams to pounds using the formula above.

pounds = (500,000 mg × 2.2046E-6) = 1.102311 lb

What Is a Pound?

Pounds are a widely used unit of weight in the United States. The National Bureau of Standards approved the international definition of the pound for use in the United States in 1959 after an agreement between six nations referred to as the International Yard and Pound Agreement.[1]

One pound is equal to 16 ounces, or 0.45359237 kilograms. In the avoirdupois or apothecaries' systems, one pound is equal to 7,000 grains.[2]

The pound is a US customary and imperial unit of weight. A pound is sometimes also referred to as a common ounce. Pounds can be abbreviated as lb (plural lbs), and are also sometimes abbreviated as lbm or #. For example, 1 pound can be written as 1 lb, 1 lbm, or 1 #, and 2 pounds can be written as 2 lbs.
