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.

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.

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

Frequently asked questions
How many pounds are in a stone?
One stone is 14 pounds. Multiply the stone value by 14 to convert. For example, 10 st = 140 lb.
What is the formula to convert stones to pounds?
lb = st × 14. This tool applies it automatically and shows a worked example: 10 st = 140 lb.
Can it convert pounds back to stones?
Yes. Press the swap button, or type into the pound field, and the tool converts pounds to stones using the inverse of the same relationship.
Is the conversion accurate?
It uses the standard mass and weight definition (lb = st × 14), not a rounded approximation, so results are exact to the number of decimal places you select.
Does this work offline and stay private?
Yes. The converter is a browser-side script with no network calls: your values are never uploaded, and once the page has loaded it keeps working without a connection.
