2Metric Conversion Tables
The bold figures in the central columns can be read as either the metric or the British Imperial measure. Thus 1 inch = 2.54 centimetres; or 1 centimetre = .3937 inch.
For tens, move decimal point one place to the right, for hundreds two places, etc. Then convert higher quantities thus : 2ft. 9 in. = 33 in = 76.2 cm + 7.62 cm. = 83.82 cm.
