1 t = 157.473 st (metric ton → stone)
1 t = 157.473 st
1 metric ton equals 157.473 stones. To convert metric tons to stones, multiply the metric ton value by 157.473. For quick reference: 1 t = 157.473 st, 5 t = 787.365 st, 10 t = 1574.73 st, 100 t = 15747.3 st.
Metric tonnes to stones multiplies by about 157.473 (1000 kg ÷ 6.35029318 kg/st). A 0.1 t (100 kg) load is 15.75 st; a full tonne is 157.47 st. The stone is a body-weight unit in the UK and Ireland, not a freight unit, so this conversion is mostly a curiosity — useful when a combined passenger weight limit quoted in tonnes needs a stones sanity check. For anything commercial, go via kilograms; the stone is no longer legal for trade in the UK.
This one shows up almost exclusively in UK agricultural and livestock contexts, where a delivery of feed or fertiliser is invoiced in tonnes but a farmer sizing up individual animal loads still thinks in stones — 1 t is 157.47 st, 0.5 t is 78.74 st, and 2 t is 314.95 st. Given the large gap between the units, this conversion is more useful for sanity-checking an order size against familiar stone-scale intuition than for any precise dosing or portioning task.

A small passenger car weighs about 1.5 t. A young African elephant weighs around 2 t. In stones, that gives you: 1 t = 157.473 st, 10 t = 1574.73 st, 100 t = 15747.3 st.
The metric ton, or tonne (t), equals exactly 1,000 kilograms. It is the standard unit for industrial shipping, freight, and bulk commodities such as steel, grain, and cement. Despite the name, it is not part of the strict SI system (the SI name is the megagram), but it is universally accepted in commerce and engineering.
The stone (st) equals exactly 14 pounds (about 6.35 kg). It is still widely used in the United Kingdom and Ireland to state body weight, even though it is no longer legal for trade. The stone was originally a real stone used by merchants as a counterweight on balances; its weight varied by region and trade until standardized in the late 19th century.
