example 1. Convert the following into millilitres.
a. 3 L b. 12 L c. 24 L 2 mL
Solution. a. 3 L = (3 × 1000) mL = 3000 mL
b. 12 L = (12 × 1000) mL = 12000 mL
c. 24 L 2 mL = 24 L + 2 mL = (24 × 1000) mL + 2 mL
= 24000 mL + 2 mL = 24002 mL

example 2. Convert:
a. 8 kL into litres b. 6 kL 350 L into litres c. 9 L 26 mL into mL
Solution. a. 8 kL = (8 × 1000) L = 8000 L
b. 6 kL 350 L = (6 × 1000) L + 350 L = 6000 L + 350 L = 6350 L
c. 9 L 26 mL = (9 × 1000) mL + 26 mL = 9026 mL

Conversion of Smaller units of Capacity into Bigger units

To convert a smaller unit into a bigger unit, we divide.

example 3. Convert the following into litres and millilitres.
a. 3000 mL b. 2340 mL c. 5075 mL
Solution. a. 3000 mL = (3000 ÷ 1000) L = 3 L
b. 2340 mL = 2000 mL + 340 mL = (2000 ÷ 1000) L + 340 mL = 2 L 340 mL
c. 5075 mL = 5000 mL + 75 mL = (5000 ÷ 1000) L + 75 mL = 5 L 75 mL

example 4. Convert:
a. 8000 L into kL b. 5656 L into kL and L
c. 7028 mL into L and mL
Solution. a. 8000 L = (8000 ÷ 1000) kL = 8 kL
b. 5656 L = 5000 L + 656 L = (5000 ÷ 1000) kL + 656 L = 5 kL 656 L
c. 7028 mL = 7000 mL + 28 mL = (7000 ÷ 1000) L + 28 mL = 7 L 28 mL

2. Convert the following into mL.

a. 13 L b. 16 L c. 11 L d. 15 L 350 mL
e. 26 L 50 mL f. 116 L 580 mL
