Rendered to 6 significant figures.
Formula
Formula
t = st × 0.00635029
Multiply any value in stones by 0.00635029 to obtain the value in metric tonnes.
Worked example
Convert 1000 st to t.
- 01Start with 1000 st.
- 02Multiply by the conversion factor: 1000 × 0.00635029 = 6.35029 t.
Result1000 st = 6.35029 t

FAQ
What is the conversion factor from st to t?
1 st equals 0.00635029 t. To convert, multiply the value in stones by 0.00635029.
How do I convert 1 st to t?
1 st = 0.00635029 t. For any value, multiply by 0.00635029.
How do I convert t back to st?
Divide by the same factor — or equivalently, multiply by 157.4731. So 1 t = 157.473 st.
When would I need to convert stone (UK avoirdupois) to metric tonne?
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).
