Tons to Ounces Converter

Tons to Ounces

Convert tons (t) to ounces (oz). Both measure mass and weight, and the conversion comes up in cooking, shipping, fitness work.

The Formula

`` ounces = tons × 35273.9619496 tons = ounces × 0.000028349523125 `

One ton is 35,273.96 ounces, and one ounce is 2.8350e-5 tons.

What Each Unit Is

Tons (t) — here the metric tonne: exactly 1,000 kilograms. From the tun, a large wine cask, whose weight became a trade standard.

Ounces (oz) — one sixteenth of a pound, or exactly 28.349523125 grams. From uncia, one twelfth — of the Roman libra, before avoirdupois moved it to one sixteenth.

A Sense of Scale

• A small car is about 1.5 t
• A cubic metre of water is 1 t
• Shipping freight is priced per tonne
• A slice of bread is about 1 oz
• A tennis ball is 2 oz
• US recipes use ounces for dry goods

Precision

The factor 35273.9619496 is rounded. For engineering work carry more digits than the table above, and round only at the end — rounding at each step compounds.

Watch Out For

• Three different tons exist: metric (1,000 kg), US short (907 kg) and UK long (1,016 kg). This converter uses the metric tonne.
• A fluid ounce measures volume, not mass, and the two are only interchangeable for water by coincidence of scale.

In Code

`javascript const tonToOunce = (value) => value * 35273.9619496; ``

How Many Decimals Do You Need?

Rounding the factor costs accuracy, and how much depends on the factor. Converting 137 t with the factor truncated at each decimal place:

Decimals kept	Factor	137 t becomes	Error
0	35274	4,832,538	0.0001%
1	35274	4,832,538	0.0001%
2	35273.96	4,832,532.52	—
3	35273.962	4,832,532.79	—
4	35273.9619	4,832,532.78	—

A rule that holds for any conversion: round once, at the end. Rounding the factor and then multiplying compounds the error through every subsequent calculation, while carrying full precision and rounding the final answer does not.

The right number of significant figures is set by your input, not by the converter. If you measured tons to three significant figures, the answer in ounces is only good to three — writing more digits claims precision the measurement never had.
