Convert metric units of length, weight, and volume with this educational worksheet.

1) 3 km = 3000 m
2) 2 cm = 20 mm
3) 4000 g = 4 kg
4) 300 mL = 0.3 L
5) 3 L = 3000 mL
6) 7 g = 7000 mg
7) 8 L = 8000 mL
8) 9 mm + 10 cm = 109 mm
9) 5 cm = 50 mm
10) 3 m = 300 cm

Which is the most? Circle the largest amount in each box.
- 3100 g
- 3240 mL
- 7 kg
- 2300 mL

Use greater than (>), less than (<) or equals (=) to compare the amounts.
11) 3000 g > 500 mL
12) 2 kg > 50 mm
13) 500 mL < 800 cm
14) 1 L > 8 cm
15) 65 mm < 6 cm
16) 81 mL > 71 dg
17) 800 mL > 800 mL
18) 2 km > 320 cm
19) 100 > 6 km
20) 460 m < 700 mm
21) 6000 g > 6 kg
22) 120 > 7 cm
