Scale: Conversion sheet
Any map you use will always be measured in centimetres (cm) first. You then need to
convert this measurement into kilometres (km), using the scale of the map. Use the
following steps to help you:
Step 1: Measure the distance, i.e. one point to another and write your answer in
centimetres (cm) below.
…………………………………….cm
Step 2: Take your answer from step 1 and times (x) it by the scale of the map
HINT: Scale can be written in numbers, words or a scale line
………………………. cm X …………………………… (scale of map)
= Answer ……………………………………………………………. cm
Step 3: Your answer from step 2 is still in centimetres (cm). To convert this into
kilometres (km) divide (÷) your answer from step 2 by 100,000 (as there are100,000 cm in
1 km)
HINT: Take off 5 0’s or move your decimal place 5 places to the left
Answer from step 2 …………………………………………….……….. cm
÷ 100,000
= Answer………………………………………….. km
This is your final answer!
