How to convert st to g
g = st × 6,350.29318. The scale factor is the source-unit factor divided by the destination-unit factor.
Worked example
For a parcel mass or material quantity of 5 st converts to 31,751.4659 g.
- Start with 5 st.
- Multiply 5 by 6,350.29318.
- Report 31,751.4659 g, rounded to the precision of your original measurement.

1 g = 0.0001574730444 st. Use the gram to stone converter to calculate in the opposite direction. This has its own formula and reference table.
Definitions that matter
Pounds and ounces here are avoirdupois units, not troy units for precious metals. A tonne is 1,000 kg; it is not a US short ton or imperial long ton. Mass is not gravitational force.
The base unit for this category is kg. One st corresponds to 6.35029318 kg; one g corresponds to 0.001 kg. These definitions explain the relationship rather than relying on a rounded display value.
Sources and precision
Definitions: NIST Guide to the SI. Calculations use double precision; the tool defaults to a readable rounded result, while tables show up to ten significant digits. Displaying more digits does not increase the accuracy of the original measurement.
