FAQ
What is the conversion factor from st to kt?
1 st equals 6.35029e-6 kt. To convert, multiply the value in stones by 6.35029e-6.
How do I convert 1 st to kt?
1 st = 6.35029e-6 kt. For any value, multiply by 6.35029e-6.
How do I convert kt back to st?
Divide by the same factor — or equivalently, multiply by 157473.1. So 1 kt = 157473 st.
When would I need to convert stone (UK avoirdupois) to kiloton (metric)?
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).
