How tall is 174cm in feet"inches

5' 8.5"

to convert cm to in, divide by 2.54 cm
because 2.54 cm = 1 inch
If we're starting with a quantity that has cm in the numerator (as we do with 174 cm), then we want our conversion factor to have cm in the denominator. so from our equation, we divide both sides by 2.54 cm and we get
1 = 1 in / 2.54 cm
notice the left side is 1, and recall that when you multiply a quantity by 1, it doesn't change the value.
so 174 cm * 1 = 174 cm
but instead, let's use the equivalent form of 1 which is given on the right side of the equation.
this time we multiply 174 cm by 1 in / 2.54 cm
174 cm (1 in / 2.54 cm) = 68.5 in (rounded to the nearest tenth, which is sufficient for this problem)

knowing that 12 in = 1 ft, we can do a similar thing
68.5 in (1 ft / 12 in) = 5 ft and some fraction (your calculator will display 5.708333333...)
subtract the 5 from that number and then multiply it by 12 in / 1 ft and you'll get 8.5 in
so answer is 5' 8.5"

2.54 cm to one inch

174/2.54 = 68.54 inches

68.54 / 12 = 5.7

Roughly 5 feet 8 inches

174/30.48 = 5 ft 8.5 inches
