Worked out from NIST Special Publication 811, Guide for the Use of the International System of Units - the 1959 international yard and pound agreement fixes 1 grain = 64.79891 mg exactly, so 1 troy ounce = 480 grains = 31.1034768 g and 3 other sources.
The spot price you entered is the only price used. It carries no dealer spread, refining charge or assay, and the result is not a quote.
A metal-content valuation only. It uses the spot price you enter, applies no bid/ask spread, refining loss, assay, numismatic premium or tax, and is not an offer or an appraisal.

How this is worked out

4 steps
  1. Gross weight = 10 g = 10 g.
  2. Fine metal = 10 g x 0.583333 = 5.8333 g.
  3. Fine metal = 5.8333 g / 31.1034768 g per troy ounce = 0.18755 ozt.
  4. Melt value = 0.18755 ozt x 2400 = 450.11.
