Divide by the same factor — or equivalently, multiply by 1.020409e-5. So 1 gr = 1.02041e-5 st.
When would I need to convert stone (UK avoirdupois) to grain (troy/apothecary)?
Mass conversions appear in material balances, reagent dosing, and reconciling vendor specifications across imperial/metric systems.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
