Table 170: Inches/feet-to-centimeters conversion. For millimeters, after inches are converted to
centimeters, move the decimal point one place to the right; so 1.0 in. = 25.4 mm. To convert inches (or
feet) to meters after inches (or feet) are converted to centimeters, move the decimal point two places to
the left; so 48 in. = 1.2 m.
