Converting between litres and millilitres using multiplication and division by 1000.
Where your child meets this in real life: Understanding drink bottle sizes (e.g., 500 ml = 0.5 litres)
SEAGReady breaks convert capacity units into 2 steps, taught in order so each skill builds on the last.
Convert whole numbers of litres to millilitres using the 1 L = 1000 mL relationship
Convert millilitres to litres by dividing by 1000, including amounts that result in decimal litres (e.g., 500 mL = 0.5 L, 2500 mL = 2.5 L)
Three free sample questions from our convert capacity units course. Every question comes with a full explanation, and hints that guide without giving the answer away.
Jack's water amount is shown. How many millilitres is this?
Sam's bottle amount is shown. How many litres is this?
A recipe needs 4 litres of stock for soup. How many millilitres of stock is this?
This is the exact interactive worked example your child sees in SEAGReady. Step through it and watch the method build up.
Megan is making punch for a school party. The recipe needs 3 litres of lemonade.
How many millilitres of lemonade does she need?
3 L = ? mL
1 litre = 1000 millilitres
Step 1 of 4
Megan is making punch for a school party. The recipe needs 3 litres of lemonade.
How many millilitres of lemonade does she need?
Megan needs 3000 mL of lemonade.
The key insight: Each litre adds 1000 millilitres - just multiply the number of litres by 1000!
Common mix-up: 3 L = 300 mL. There are 1000 mL in a litre, not 100. Milli- means thousandth, not hundredth.
These are the misconceptions we see most often in convert capacity units, including the ones our practice questions are specifically designed to catch.
Struggling with convert capacity units? The real gap is often in one of these earlier topics.
SEAGReady finds the exact step where your child gets stuck, teaches it with worked examples like the one above, and brings it back for review so it sticks.
