I hope this helps a bit, are you able to get rulers from your stationery store that has centimetres and milimetres? Then you could just put it on your inch ruler and convert them that way.
No need to go to stationary store--------------USE YOUR OWN rulers that you already have. The straight rulers have metric measures on one side, inches on the other.
