Feet and inches are converted to centimeters using the exact definitions:
- 1 foot = 30.48 centimeters
- 1 inch = 2.54 centimeters
If F is feet and I is inches, then total centimeters:
cm = F × 30.48 + I × 2.54Meters are obtained by dividing centimeters by 100. The displayed value respects your selected decimal places and rounding mode; the exact value is also shown for reference.

1) Can I enter fractional feet or inches?
Yes. Both fields accept decimals like 5.75 feet or 7.5 inches. The calculator converts them precisely using the exact centimeter definitions.
2) What rounding does the tool use?
By default it uses standard rounding. You can switch to floor or ceiling. The exact centimeter value is shown separately for reference.
3) Why does the exact value differ from the displayed value?
The exact value is the full precision calculation. The displayed value is formatted according to your selected decimal places and rounding mode.
4) Can I export multiple results at once?
Yes. Add several rows using Add to Table. Then export the entire table to CSV or PDF.
5) Are centimeters and meters both available?
Yes. Results show both centimeters and meters. You can also toggle the primary output unit.
6) Do negative inputs work?
No. Physical lengths should be non‑negative. The inputs prevent negative values.
7) Is this suitable for professional use?
Yes. The calculator uses exact conversion constants and offers explicit rounding control suitable for engineering education laboratory and everyday contexts.
