Feet + Inches to Centimeters – Fast Height Conversion Guide
Core idea: Convert the mixed value to total inches, then to centimeters. Exact factors: 1 in = 2.54 cm, 1 ft = 12 in = 30.48 cm. Formula shortcut: cm = feet×30.48 + inches×2.54.
Formulas

Quick Height Values
| Feet+Inches | Total Inches | cm | Meters |
|---|
| 5' 4" | 64 | 162.56 | 1.6256 |
| 5' 5" | 65 | 165.10 | 1.6510 |

Accuracy & Tips
- All factors are exact (international yard definition).
- Mental: 1 inch ≈ 2.5 cm (slight under); add 2% to refine.
- To reverse: split cm by 30.48 to get feet, remainder ÷ 2.54 → inches.
