Grams to Pounds Calculator (Mass)

Grams and pounds have found a place in our lives as units of weight and mass.

A gram to pound calculator converts weight measurements within the metric system or to the imperial system (and vice versa).

It's a helpful tool to convert measurements when you don't know the conversion rates. This is a dilemma that has faced nations since ancient Rome.

For every one gram you have, it equals 0.0022lbs. That means a gram is 0.2% of a pound. To think of it the other direction, 0.0022 pounds are in one gram. The equation to convert is as follows:

Pounds = grams x 0.0022

Steps

1. When you want to convert g to lb, start with your number of total grams.

2. Take that number and multiply it by .0022.

The resulting number will give you the weight in pounds.

Let's walk through a few common conversions.

200 grams to pounds

This is equal to 0.44 pounds.

1300 grams to lb

This is equal to 2.86lb

1500 g to lbs

This is equal to 3 pounds.

Pounds to grams

In each pound you have, there’s 453.59237 grams. Multiplying by that number will get you the conversion. Rounding up to one or two decimal places (i.e. 453.6) may seem convenient, but you’ll get more exact results by using the 6-decimal multiplier.

The equation to convert:

g = lb x 453.59237

Steps

1. To convert, start with your number of total pounds.
 
2. Take that number and multiply it by 453.59237.
 
3. The resulting number will give you the weight in grams.

Let’s do a few basic examples together to get a better understanding of this concept.

2 pounds to g

This is equal to 907.18474 grams.

1/4 lb to grams

This is equal to 113.3980925 g.

1.65 lb to g

This is equal to 725.747792 gram.

Bottom Line

As you can see, the conversion itself is simple. The only pitfall to calculating lb to g is remembering the multiplier and its decimal values.

An online converter can help you power through the task with ease. And you won’t have to worry about typos or errors in translation throwing off your results. If you try the conversions by hand, we recommend checking your work with your favorite online conversion calculator.

A gram is the mass unit in the small unit metric system. This system consists of centimeters, grams, and seconds (cgs).

Grams are one unit that expresses mass. Use a prefix multiplier of 10 to change grams to a smaller or larger unit.

Kilograms

Kilograms are the si units of mass. If you have 1,000 grams, that equals 1 kilogram. Or to think of it in the other direction, 1 gram equals .001 kilograms.

Milligrams

Going smaller in measurement, 1 gram equals 1,000 milligrams. If you have 1 milligram, you have .001 of a gram.

Microgram

If you have 1,000 micrograms, it equals 1 milligram. This means that you need 1e+6, or 10 to the power of -6 in grams.

Nanogram

A nanogram is the smallest measurement. It equals 10 to the power of -9 in grams.

Lb is a unit of measurement for mass in the United States customary and Imperial units system. Today, the definition used is the international avoirdupois pound.

One of these pounds equals 0.45359237 kilograms. This conversation rate is from an agreement in 1959. The US and the Commonwealth of Nations agreed to a standard definition for easier use.

The Avoirdupois Pound

Back in 1300, the wool pound came into use. Today we know it as the Avoirdupois pound.

It was initially used to refer to 6,992 troy grains. It was later redefined as 7,000 grains. Grains here refers to actual grain. Merchants used grains to define the mass of other goods.

In the 1500s this method got a new definition. The new definition used gold and a barley-corn grain as the basis.

The pound has referred to a unit of mass across the world, at different times, and different amounts. The first recorded use is from Rome.

In ancient Rome, a unit called a libra designated a mass of 328.9 grams. The libra is the origin for the "lb" abbreviation for the pound.

Other Uses of Pound

Throughout history, the pound has had a version in France, Germany, and Russia. Great Britain alone has used 6 different versions of the pound. The majority of which are obsolete today.

Grams are a measurement used when needing precise amounts of smaller quantities. Pounds work when measuring the weight of larger items.

Cooking

Pounds are not used in cooking unless it is in an industrial application. Grams are often used in countries where the metric system is the standard.

Health and Fitness

In the United States, pounds is the method of measurement for expressing a person's weight. The United Kingdom is similar but uses a "stone" system. In this system, 1 stone equals 14 pounds.

The gram is a common method of measurement for nutrition. You will often see it used to express the amount of protein or fat required in a day.

Metals

Grams are often used to measure the weight of precious metals. Pounds are too large of a measurement for these metals.

Pressure

Pounds can measure the amount of force or pressure applied to one square inch. It refers to pound-force per square inch or psi.

If you see psia, this refers to the pressure measured as if it were in a vacuum. Whatever the pressure is, 14.7 gets added. This extra pressure is the standard atmospheric pressure at sea level.

If you see psig, the means the pressure is relative to the atmospheric pressure. To see the difference, a bicycle tire has a pressure of 65 psi. To make this absolute, add 14.7. The absolute pressure of the tire is 79.7psia.
