About this tool

Foot to Inch Converter

Convert feet to inches instantly. Free, bidirectional, and fully in-browser.

1 foot equals 12 inches — enter any foot value to convert it to inches instantly. This Foot to Inch converter is a client-side tool: it applies a single multiplication (in = ft × 12) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert inches back to feet. A reference table lists common foot values already converted, and nothing you enter is sent to a server.

Why use Foot to Inch Converter

• Instant, both ways

  The result updates as you type, and the swap button flips the conversion to inch → foot without reloading.

• Exact Length math

  The conversion uses the precise factor (in = ft × 12), so the number matches a manual calculation to the decimal places you choose.

• Adjustable precision

  A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.

• Private and free

  Everything runs locally in your browser — no upload, no account, no limit on conversions.

Common use cases
