Type a weight and pick its unit. See it in kg, pounds, grams, ounces, tola, quintal and tonne at once.

A weight converter uses exact factors from NIST SP 811, such as 1 pound = 0.45359237 kg, plus 1 tola = 11.6638038 g for gold. 70 kg is 154.3236 pounds, and 10 tola is 116.638 grams.

How to use this weight converter

Type the weight you have, such as 70 or 2.5.
Under From, pick its unit: kg, pounds (lb), tola and so on.
Under To, pick the unit you want. The big number is your answer, and the table shows all the other units.
Tap Swap units to go the other way, for example from pounds back to kg.

Weight conversion formula

Result = W × (grams in one "from" unit) ÷ (grams in one "to" unit)

W: The weight you type.
1 pound (lb): Exactly 0.45359237 kg.
1 ounce (oz): One-sixteenth of a pound: 28.349523125 g.
1 tola: 180 grains, which is 11.6638038 g.
1 quintal: 100 kg. A tonne is 1,000 kg, so 10 quintals make a tonne.

Every unit is turned into grams first, then into the unit you want. The factors are exact, so the only rounding is in the digits we show.

Worked examples

Kg to pounds. One pound is 0.45359237 kg. So 70 kg = 70 ÷ 0.45359237 = 154.3236 lb.

Gold weight: 10 tola
Grams in one tola: 11.6638038 g
10 tola in grams: 116.638 g

So 10 tola is a little more than 116 grams, not 100 grams.

Tola and gold weights

The tola is a traditional Indian weight, still used for gold and silver. One tola is 180 grains, or about 11.66 g. Many jewellers today quote gold prices per 10 grams instead, so check which unit a price uses.
