Example 7.52 from Prealgebra, 7.5 Systems of Measurement

Systems of Measurement: example 7.52

Convert:

ⓐ $350$ liters to kiloliters
ⓑ $4.1$ liters to milliliters.

Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.

Solution
ⓐ We will convert liters to kiloliters. In Table 7.3, we see that $1 kiloliter = 1000 liters .$

350 L

Multiply by 1, writing 1 as a fraction relating liters to kiloliters.

Simplify.

Move the decimal 3 units to the left.

0.35 kL

ⓑ We will convert liters to milliliters. In Table 7.3, we see that $1 liter = 1000 milliliters.$

4.1 L

Multiply by 1, writing 1 as a fraction relating milliliters to liters.

Simplify.

Move the decimal 3 units to the left.

4100 mL

Your turn

The book's Try It right after this example: same idea, new numbers. Only the answer is given.

Convert: ⓐ $7.25$ L to kL ⓑ $6.3$ L to mL.
