Lesson 185 of 216
Concept
Common metric ladders: - Length: km, m, cm, mm - Mass: kg, g - Volume: L, mL
Conversions: - 1 m = 100 cm - 1 km = 1000 m - 1 kg = 1000 g - 1 L = 1000 mL
Compare by converting to same unit first. Example: 2.5 m and 240 cm 2.5 m = 250 cm, so 2.5 m > 240 cm.
Try it
Convert and compare: 1. 3.4 m to cm 2. 850 g to kg 3. 2.75 L to mL 4. Which is larger: 1.2 km or 1150 m? 5. Which is larger: 0.9 kg or 950 g?
