Background
About feet and inches
The US and UK give heights as feet and inches, twelve inches to the foot; everywhere else uses centimeters. One inch is exactly 2.54 cm, so 5′ 10″ (70 inches) is 177.8 cm.
To convert by hand, turn the height into inches first: feet × 12 + inches, then multiply by 2.54.
