Formula & Theory — Height Inches Calculator
The Height Inches Calculator applies exact conversion factors in both directions:
—— Imperial → Metric ——
total_in = feet × 12 + inches
cm = total_in × 2.54
m = cm / 100
—— Metric → Imperial ——
total_in = cm / 2.54
feet = floor(total_in / 12)
remain_in= total_in − feet × 12| Symbol | Meaning | Unit |
|---|---|---|
| feet | Whole feet component | ft |
| inches | Remaining inches (0–11.999) | in |
| total_in | Total height expressed in inches | in |
| cm | Height in centimetres | cm |
| m | Height in metres | m |
Key Conversion Constant
1 international inch = exactly 2.54 cm (no rounding — this is a defined exact value).
