About this tool

Stone to Grain Converter

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

1 stone equals 98000 grains — enter any stone value to convert it to grains instantly. This Stone to Grain converter is a client-side tool: it applies a single multiplication (gr = st × 98000) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert grains 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 Grain Converter

  • Instant, both ways

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

  • Exact Mass math

    The conversion uses the precise factor (gr = st × 98000), 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

  • Converting a stone measurement to grains for a spec, listing, or report.
  • Checking stone↔grain figures while comparing products, datasets, or documentation.
  • Learning the stone-to-grain relationship from the worked formula and the common-value table.

Frequently asked questions

How many grains are in a stone?

One stone is 98000 grains. Multiply the stone value by 98000 to convert. For example, 10 st = 980000 gr.

What is the formula to convert stones to grains?

gr = st × 98000. This tool applies it automatically and shows a worked example: 10 st = 980000 gr.

Can it convert grains back to stones?

Yes. Press the swap button, or type into the grain field, and the tool converts grains to stones using the inverse of the same relationship.

Is the conversion accurate?

It uses the standard mass and weight definition (gr = st × 98000), 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.
