Key Concepts — Quick Reference
This chapter
Units of capacity (the one fact everything rests on)
| Litre and millilitre | 1 litre (L) = 1000 millilitres (mL) |
|---|---|
| Half a litre | 1/2 L = 500 mL |
| Quarter litre | 1/4 L = 250 mL |
| Three-quarter litre | 3/4 L = 750 mL |
| Kilolitre (rarely tested) | 1 kilolitre (kL) = 1000 L |
Capacity concepts and operations
| Capacity vs volume | Capacity = how much a container HOLDS (usually liquid, in L/mL) |
|---|---|
| More / less (early idea) | Compare by pouring into identical containers; shape can mislead |
| Litre to millilitre | Multiply by 1000 (move 3 places, e.g. 2 L = 2000 mL) |
| Millilitre to litre | Divide by 1000 (e.g. 3500 mL = 3 L 500 mL) |
| Mixed measure | Add/subtract mL with mL; carry/borrow at 1000 (1000 mL = 1 L) |
