This converts standing height between common units. It does not predict adult height, diagnose growth, or include shoes.
Quick reference: height units
1 inch = 2.54 cm exactly. 1 foot = 12 inches.
| Item | Detail |
|---|---|
| ft+in → cm | (ft × 12 + in) × 2.54 |
| cm → ft+in | divide by 2.54, split into ft and in |
| Meters | cm ÷ 100 |
| 5′10″ | 70 in = 177.8 cm |
Hair and footwear are not part of clinical height rules.
How the estimate is built
total_in = ft×12 + in; cm = total_in × 2.54; m = cm/100.
Example scenario
5′10″ → 177.8 cm (70 in).
FAQ
Can this estimate how tall my child will be?
No. It only converts units for a height you already measured.
Does BMI use these units?
BMI pages expect weight and height in consistent units; convert here first if needed.
Why show total inches?
Some charts and formulas want one number like 70 in instead of 5 ft 10 in.
