Metric capacity conversion, step by step

Milliliters and liters are the metric measures of how much a container holds — a water bottle, a carton of juice.

The question
919 L = ________ mL

19 L = ? mL

L → mLsmaller unit, bigger number
1 L =1000 mL
19 × 1000 =19000
19000 mL
  1. One mL is smaller than one L, and it takes MORE of a small thing to make the same amount. So the number has to get bigger — which means multiplying.
  2. There are 1000 mL in one L, so that is the number to multiply by.
  3. 19 × 1000 = 19000, so 19 L is 19000 mL. Check the direction held: the number got bigger, which is what a smaller unit does.

How it works.

  1. 01

    One mL is smaller than one L, and it takes MORE of a small thing to make the same amount. So the number has to get bigger — which means multiplying.

  2. 02

    There are 1000 mL in one L, so that is the number to multiply by.

  3. 03

    19 × 1000 = 19000, so 19 L is 19000 mL. Check the direction held: the number got bigger, which is what a smaller unit does.
