Weight Conversion
Here are useful units of measure to know
Example 1: Unit conversion (English system)
Do the following conversions. Round to nearest tenth where necessary. 80 oz = lb We know that 1 pound (lb) = 16 ounces (oz) so 80 oz × = × = 5 lb So, 80 oz = lb
We know that 1 pound (lb) = 16 ounces (oz) so
So, 80 oz = lb
Example 2: Unit conversion (metric system)
Do the following conversions. Round to nearest tenth where necessary. 3 kg = g We know that 1 kilogram (kg) = 1000 grams (g) so 3 kg × = × = 3000 g So, 3 kg = g
We know that 1 kilogram (kg) = 1000 grams (g) so
So, 3 kg = g
Example 3: Unit conversion (English and metric systems)
Do the following conversions. Round to nearest tenth where necessary. 1 ton = g To convert between the two systems, we know that 1 kilogram (kg) = 2.2046 grams (g). There are multiple steps: tons --> pounds --> kilograms --> grams Step 1: Convert tons (T) to pounds (lb) by multiplying 2000 lb / 1 ton 1 ton × Step 2: Convert pounds (lb) to kilogram (kg) by multiplying 1 kg / 2.2046 lb 1 ton × × Step 3: Convert kilograms (kg) to grams (g) by multiplying 1000 g / 1 kg 1 ton× × × Step 4: Solve the equation 1 ton × × × = 1 ton × × × = 907,193.6 g So, 1 ton = g Copyright Accurate Learning Systems Corporation 2008.MathScore is a registered trademark.

1 ton ×
1 ton × ×
1 ton× × ×
1 ton × × × = 1 ton × × × = 907,193.6 g So, 1 ton = g
So, 1 ton = g
