Tips for Accurate Height Conversion

When you convert a feet-and-inches height to centimeters, always convert the two parts separately and add them. The factor 30.48 handles the feet, and 2.54 handles the inches. Rounding too early, such as approximating 5'11 as 5.11 feet, introduces error because 0.11 feet is not 11 inches.

A second tip is to remember that 5'11 is not the same as 5.11 feet. The notation 5'11 means 5 feet plus 11 inches, while 5.11 feet is 5 feet plus 0.11 of a foot, which is about 1.3 inches. Always treat the inch portion as a separate value, multiply by 2.54, and add it to the foot portion converted by 30.48.

A third tip is to use the total-inches shortcut for a single multiplication. Convert the full height to inches first, then multiply by 2.54. For 5'11, that is 71 inches times 2.54, equaling 180.34 cm. The shortcut gives the same exact result as the two-part method and is often faster at the calculator.
