FAQ

What is the conversion factor from g to dr?
1 g equals 0.5643834 dr. To convert, multiply the value in grams by 0.5643834.
How do I convert 1 g to dr?
1 g = 0.564383 dr. For any value, multiply by 0.5643834.
How do I convert dr back to g?
Divide by the same factor — or equivalently, multiply by 1.771845. So 1 dr = 1.77185 g.
When would I need to convert gram to dram (avoirdupois)?
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).
