What this calculator does
- Feet & Inches to CM Converter
- Convert ft/in to centimeters and reverse with inch precision.
Height questions on international paperwork often want centimeters while people still think in feet; the reverse mode splits total inches back into feet plus fractional inches.
Height-style conversion: combine feet and whole inches to centimeters, or convert centimeters back to feet and fractional inches for display.
Inputs on this page: Direction, Feet (use 0 when converting from cm only), Inches (0–11 typical when paired with feet), Centimeters (cm→ft/in mode). Assumptions stay visible so you can reproduce the figure elsewhere.
When to use it
- Use Feet & Inches to CM Converter when you need a transparent feet inches to cm answer before you commit numbers to a spreadsheet, invoice, or conversation.
- Reach for it when you already know (or can estimate) Direction and want the dependent result without rebuilding the formula by hand.
- Skip it when you need certified advice, signed-off payroll, or a lender’s official quote—those require the primary institution’s systems.
Key takeaways
- Normalize inches under twelve before sharing human-readable heights when possible.
- Decimal inches (ten point five) are supported for fractional shoe or clinical measurements.
- Pediatric growth charts need percentiles beyond raw conversion-this page is unit math only.

- Feet (use 0 when converting from cm only): the value you enter for feet.
- Inches (0–11 typical when paired with feet): the value you enter for inches.
- Centimeters (cm→ft/in mode): the value you enter for cm.
