One inch, the old Imperial unit of measurement, is equivalent to 2.5 centimetres, the metric unit that was introduced into the UK in 1965. So, nine inches is equivalent to nine times 2.5, which is 22.5 centimetres.

6inches=15cm

3inches=7.5cm

3*3=9inches=7.5*3=22.5cm

3inches=7.5cm

3*3=9inches=7.5*3=22.5cm

Nine inches is twenty-three centimetres.

For most practical purposes, you can reckon that one inch is 2.5 centimetres.
