Convert between miles and km, imperial and metric

Use, read, write and convert between standard units, converting measurements of length, mass, volume and time from a smaller unit of measure to a larger unit, and vice versa; convert between miles and kilometres

What you'll learn

  1. 1

    Imagine you're walking 🚶 along a road in the UK. The signs say '1 mile'. But in France, the same distance is about '1.6 km'. That's because miles and kilometres are just different ways to measure the same length!

  2. 2

    If 1 mile is about 1.6 km, how many km is 2 miles?

  3. 3

    Drag the marker on the number line to show 5 miles. Each big jump is 1 mile. Then see how many km that is!

  4. 4

    Let's change 8 km into miles. Remember: 1 mile = 1.6 km, so we divide by 1.6.

  5. 5

    Use the bar model to change 10 miles into km. The total bar is 10 miles. Each part is 1 mile = 1.6 km.

  6. 6

    Change 20 km into miles. (Hint: divide by 1.6)

  7. 7

    A car travels 30 miles. About how many km is that?
