22.86cm Algebraic Steps / Dimensional Analysis Formula 9 in* 2.54 cm 1 in = 22.86 cm
If that's 2.31 cm, that's about 9/10 of an inch.
175.26 centimetres. 5 feet + 9 inches = 5 (feet) x 12 (inch/feet) + 9 (inches) = 69 inches 69 (inches) x 2.54 (cm/inch) = 175.26 cm
About 172 centimeters. 69 inches * 2.54 cm/inch ~ 175cm One inch is effectively DEFINED as being 2.54 cm.
