About this tool

Stone to Pound Converter

Convert stones to pounds instantly. Free, bidirectional, and fully in-browser.

1 stone equals 14 pounds — enter any stone value to convert it to pounds instantly. This Stone to Pound converter is a client-side tool: it applies a single multiplication (lb = st × 14) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert pounds back to stones. A reference table lists common stone values already converted, and nothing you enter is sent to a server.

Why use Stone to Pound Converter

• Instant, both ways

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

• Exact Mass math

  The conversion uses the precise factor (lb = st × 14), 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
