Converting Imperial Measurement to Metric

Converting Imperial Measurement to Metric

Is there an easy way of converting imperial measurement to metric for someone who is not good at math?

Carol Reed: Sure: use a calculator and multiply your imperial inch measurement by 25.4 for the equivalent metric measurement in millimeters.

Richard Jones:¬†Apart from the useful knowledge that 10 feet is about 3 meters, 1 foot equals about 303 mm, 1″ is about 25 mm, and 4″ is about 100 mm, the easiest method I know of is to use a ConstructionMaster calculator. On the other hand I’ve been dodging between imperial measure and metric for close on thirty years, and I find that, apart from knowing some useful ballpark conversions, it’s easier to stick with one system or the other.
