What is a Pound? History, origin and usage
The pound descends from the Roman libra pondo — "a pound by weight". English kept "pound" from pondo and the abbreviation "lb" from libra, which is why the word and its symbol look unrelated. For centuries the pound differed between countries and even between trades. That ended on 1 July 1959, when the United States, United Kingdom, Canada, Australia, New Zealand and South Africa agreed a single international pound of exactly 0.453 592 37 kilograms.
The pound is the everyday weight unit in the United States and is still widely used in the United Kingdom for body weight, food and parcels. Body weight, groceries, baggage limits and shipping rates in the US are all quoted in pounds.
Because the 1959 agreement fixed the pound as an exact number of kilograms, every pound conversion on this site is exact rather than approximate. The same agreement fixed the yard at exactly 0.9144 metres — which is why it is known as the yard-and-pound agreement.
What is a Quintal? History, origin and usage
The quintal travelled a long way to reach its modern value: from the Latin centenarius, "of a hundred", through the Arabic qintar, into medieval European trade, where it meant a hundredweight of whatever the local pound happened to be. Metrication settled the argument by redefining it as exactly one hundred kilograms.
In India the quintal is the standard unit of the grain trade. Minimum support prices for wheat, paddy, pulses and sugarcane are announced in rupees per quintal, and mandi (market yard) rates are quoted the same way, so farmers, traders and policy documents all deal in quintals rather than tonnes.
Ten quintals make one tonne, which is what makes it a convenient trading size — big enough for a sack-load, small enough to price. The older non-metric "hundredweight" it descends from is still a different mass in Britain and the United States.

How to use this Pound to Quintal converter
Type a number into the Pound field and the equivalent in Quintal appears instantly — there is no “convert” button to press and nothing is sent to a server, so it works offline once the page has loaded and is safe for any data. You can also type into the Quintal field to convert the other way (quintal to pound). Use the swap control to flip the two units, and copy the result with a single click. Because the calculation runs in your browser with full floating-point precision, the converter is more exact than the rounded figures shown in the reference chart above — use the chart for quick look-ups and the tool for precise work.
Accuracy and method
Every figure on this page — the formula, the worked examples, the conversion chart and the “convert to other units” tables — is computed from a single verified conversion factor (1 lb = 0.004535924 q), never copied from a hand-typed lookup table that could drift. That factor is derived from each unit’s definition in terms of a common base unit, and an automated check re-verifies all of the site’s factors on every update, so the numbers here stay correct over time. This matters for pound-to-quintal conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.
Sources
- NIST Special Publication 811 — Guide for the Use of the SI — publishes the exact metric equivalents of the customary weight units. The 1959 international yard-and-pound agreement fixes the international avoirdupois pound at exactly 0.453 592 37 kilogram, and the ounce, stone, grain and both tons are defined as exact fractions or multiples of that pound — so every imperial weight on this page is exact, not rounded.
- BIPM — The International System of Units (SI Brochure) — the defining document for the SI, published by the International Bureau of Weights and Measures. It fixes the base unit that this conversion resolves to, which is why the factor here can be exact rather than approximate.
Weight factors here are exact, anchored to the kilogram: the international pound is exactly 0.45359237 kg, a stone is 14 pounds, a short ton is 2,000 pounds and a long ton is 2,240, a grain is 1/7000 of a pound and a metric carat is exactly 200 mg. So the live tool and every number on this page always agree.
