How the conversion works

The relationship is t = oz × 0.000028349523. Both units measure mass, so the conversion is a fixed factor that never changes. The figure is exact rather than approximate: since the international yard and pound agreement of 1959, an inch is defined as exactly 25.4 millimetres and a pound as exactly 0.45359237 kilograms, and every other imperial and US customary unit here is derived from those two.

Tonne: Also called a metric ton.
