Carat to Microgram Converter

Convert carats to micrograms instantly. Free, bidirectional, and fully in-browser.

1 carat equals 200000 micrograms — enter any carat value to convert it to micrograms instantly. This Carat to Microgram converter is a client-side tool: it applies a single multiplication (µg = ct × 200000) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert micrograms back to carats. A reference table lists common carat values already converted, and nothing you enter is sent to a server.

Why use Carat to Microgram Converter

• Instant, both ways

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

• Exact Mass math

  The conversion uses the precise factor (µg = ct × 200000), 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 carat measurement to micrograms for a spec, listing, or report.
