Weight & Mass Converter

The conversions people need most

From	To	Multiply by	Example
Kilograms	Pounds	2.204623	70 kg = 154.3 lb
Pounds	Kilograms	0.45359237	154 lb = 69.9 kg
Grams	Ounces	0.035274	500 g = 17.64 oz
Ounces	Grams	28.349523	8 oz = 226.8 g
Stone	Kilograms	6.35029318	12 st = 76.2 kg
Tola	Grams	11.6638038	10 tola = 116.64 g
Maund	Kilograms	37.3242	5 maund = 186.62 kg

The pound is defined as exactly 0.45359237 kilograms — agreed in 1959 and unchanged since — so pounds to kilograms is exact. Kilograms to pounds is the same relationship divided, which is why it never comes out round.

Doing it in your head

Kilograms to pounds: double it, add 10%. 70 kg → 140 + 14 = 154 lb. True answer: 154.3. Close enough to buy luggage with.

Pounds to kilograms: halve it, take off 10%. 154 lb → 77 − 7.7 = 69.3 kg. True answer: 69.9.

Stone to kilograms: multiply by 6, add a third of a kilo per stone. 12 st → 72 + 4 = 76 kg. True answer: 76.2.

Tola and maund

Metric units are official across Pakistan and India, but two older units remain in daily commercial use, and most international converters ignore both.

Tola — 11.6638038 grams. The standard unit for gold. When a jeweller quotes “per tola”, convert to a per-gram price by dividing by 11.6638 before comparing with an international rate. Ten tola is 116.64 g, a shade under four troy ounces.

Maund — standardised in Pakistan at 37.3242 kg, which is 40 seer of about 933 grams each. Still used for grain, sugar, cotton and produce. Be careful with historic documents: before standardisation the maund varied by region and even by commodity, sometimes by a factor of two.

Tons: three different things with one name

Unit	Pounds	Kilograms	Where
Short ton	2,000	907.18	United States
Metric tonne	2,204.6	1,000	Almost everywhere
Long ton	2,240	1,016.05	UK, historically

A long ton is 12% heavier than a short ton. On a shipment of a hundred tons that is the weight of a small car, so freight contracts state which one they mean, and so should you.

Mass or weight?

Strictly, they are different. Mass is how much matter an object contains and does not change. Weight is the force gravity exerts on that mass — take the same object to the Moon and its weight falls to about a sixth while its mass is identical.

Bathroom scales measure force and report mass, which works fine because the Earth’s gravity is near enough constant. Everything on this page is mass, and everyday language calls it weight. That is not worth correcting anyone over.

Cooking weights worth knowing

Ingredient	1 cup	In grams
Water	240 ml	240 g
Granulated sugar	—	about 200 g
Plain flour	—	about 125 g
Butter	—	about 227 g
Rice, uncooked	—	about 185 g

These are approximate on purpose: a cup measures volume, and how much a cup of flour weighs depends on whether it was scooped or spooned, and how settled it was. Anything weighed in grams is reproducible; anything measured in cups is not, which is why baking recipes that matter are written by weight.
