Convert lbs (pounds) to kilograms, stone, ounces, grams, and tons. Clarifies the lbs vs. lb abbreviation and provides a full conversion table.
This converter answers a common search query: "lbs" and "pounds" mean the same thing. "Lb" is the standard abbreviation for pound, and "lbs" is the informal plural form. Both refer to the avoirdupois pound used in everyday weight measurements. That spelling detail is helpful because many labels and search queries use the plural even when the unit is singular.
After clearing up the label, the calculator also works as a general weight converter. Enter pounds, kilograms, stone, ounces, grams, or tons and it returns the matching values across the other units. The same page therefore handles both the terminology question and the actual conversion work. It is also a quick way to cross-check weights that appear on shipping labels, fitness charts, or food packaging. If you only needed the abbreviation explained, you still get the broader converter without leaving the page.
The table is useful for quick lookups, and the stone-and-pounds display helps when you need a UK-style weight format instead of a decimal pound value.
People often search this phrase because they are unsure whether lbs and pounds are different units. This page resolves that confusion immediately and then handles the follow-on conversions to kg, stone, ounces, grams, and tons. It saves a second lookup when the real goal is a different weight unit. It is also useful when you want the abbreviation explained before doing the actual conversion.
Kilograms = Pounds ÷ 2.20462. Stone = Pounds ÷ 14. Ounces = Pounds × 16. Grams = Pounds × 453.592. US Tons = Pounds ÷ 2,000.
Result: 150 lb = 68.04 kg = 10 st 10 lb = 2,400 oz
150 pounds divided by 2.20462 gives 68.04 kg. Divided by 14 gives 10 stone with 10 pounds remaining.
The abbreviation "lb" comes from the Latin "libra pondo" ("a pound by weight"). The word "pound" comes from "pondo," while the abbreviation comes from "libra." This is why the abbreviation and the full word look nothing alike.
The everyday pound is the avoirdupois pound (453.592 g). The troy pound (373.242 g), used for precious metals, is lighter. "1 pound of gold" and "1 pound of feathers" actually use different pound definitions — leading to the classic trick question.
The US uses pounds, the UK uses stone and pounds, and most of the world uses kilograms. Converting between them is a daily need for international travelers, online shoppers, and anyone following fitness or health content from other countries.

A US (short) ton = 2,000 pounds. A metric tonne = 1,000 kg = 2,204.62 pounds. The UK (long) ton = 2,240 pounds. Those different definitions are why the unit name needs context.
Divide pounds by 14. The whole number is stone; the remainder is pounds. Example: 165 lb ÷ 14 = 11 stone 11 lb. That is the grouped UK-style answer.
