Time Conversions
9-4 Converting Metric Units
To multiply by a power of 10, move the decimal to the right; to divide by a power of 10, move the decimal to the left.
Helpful Hint
9-4 Converting Metric Units
Ex 1
Convert 450 g to _____ kg.
Write a proportion. = 450 g x kg
1,000 g m 1 kg
1,000x = 450 kg
x = 0.45 kg
The cross products are equal. Divide both sides by 1,000 to undo the multiplication.
9-4 Converting Metric Units
Ex 2
Convert.
Write a proportion. = 8,500 g t x kg
1,000 g m 1 kg
8,500 g = _____ kg
1,000x = 8,500 kg
x = 8.5 kg
The cross products are equal. Divide both sides by 1,000 to undo the multiplication.
