**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:

- 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.
- A decimeter was defined as a tenth of a meter.
- A cube with side lengths of 1 decimeter has a volume of 1,000 cm
^{3}or 1 dm^{3}. - The volume of 1,000 cm
^{3}or 1 dm^{3}is equal to 1 liter, where the definition comes from. - If we weigh 1 liter of pure water, it defines the weight of 1 kg.
- 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 cm
^{3}of pure water. - The weight of 1 ml of pure water.
