Converting Grams to Pounds and Ounces Manually

To determine the conversion rate between grams and pounds, we must first assess how many grams are in a pound.

One pound is equal to about 453.6 grams when rounded to one decimal place. Additionally, one pound consists of 16 ounces, hence 1 ounce equals about 28.3 grams when rounded to one decimal place. We can also use these rates to express the opposite values, as 1 gram is equal to 0.0022 pounds, or 0.035 ounces.

This creates the following set of formulae:

grams = pounds * 453.6
pounds = grams * 0.0022
grams = ounces * 28.3
ounces = grams * 0.035

To calculate these conversions manually, simply substitute the input value and count the missing value. Below are 4 quick examples that show how each formula is used in practice.

EXAMPLE 1: Convert 3.5 pounds into grams.

We use the first formula and substitute it as follows:

grams = pounds * 453.6 \\= 3.5 * 453.6 \\= 1,587.6 ~grams.

EXAMPLE 2: Convert 5,500 grams into pounds.

We use the second formula and substitute it as follows:

pounds = grams * 0.0022 \\= 5,500 * 0.0022 \\= 12.1 ~pounds.

EXAMPLE 3:Convert 17 ounces into grams.

We use the third formula and substitute it as follows:

grams = ounces * 28.3 \\= 17 * 28.3 \\= 481.1 ~grams.

EXAMPLE 4: Convert 220 grams into ounces.

We use the fourth formula and substitute it as follows:

ounces = grams * 0.035 \\= 220 * 0.035 \\= 7.7 ~ounces.

What is a Gram?

The gram is a basic unit of mass in the metric system. The definition of a gram is connected with the natural world, by defining some specific rates to other units of measurement. Let’s have a look at how the definition of a gram was created:

  1. In the year 1793, the meter was defined as one ten-millionth of the distance between the Equator to the North pole along the Great circle.
  2. A decimeter was defined as a tenth of a meter.
  3. A cube with side lengths of 1 decimeter has a volume of 1,000 cm3 or 1 dm3.
  4. The volume of 1,000 cm3 or 1 dm3 is equal to 1 liter, where the definition comes from.
  5. If we weigh 1 liter of pure water, it defines the weight of 1 kg.
  6. A kilogram is defined as 1,000 grams (the Latin prefix ‘kilo’ means a thousand of something), hence a gram is defined as any of the following:
    • A thousandth of a kilogram.
    • The weight of 1 cm3 of pure water.
    • The weight of 1 ml of pure water.
