Formula to convert feet to inches
One foot is exactly 12 inches. So to go from feet to inches, multiply by 12:
| d(in) = d(ft) × 12 |
To write the result in feet and inches, split off the groups of 12 inches: each group is one foot and what is left over is inches. To convert to centimeters, multiply the feet by 30.48; the value is exact because since 1959 the international foot has been defined as 0.3048 meters.
