A pound, abbreviated as "b," is a unit of weight commonly used in the United States and a few other countries that follow the imperial system. The term "pound" comes from the Latin word libra, which is why the abbreviation is "lb.”
One pound is equal to 16 ounces or approximately 0.4536 kilograms in the metric system. It's often used for measuring body weight, grocery items, shipping packages, and more in everyday American life.
The pound dates back to Roman times and has evolved through various systems. The current definition used in the U.S. is based on the avoirdupois system, which standardizes one pound as 16 ounces. This system has been in use in English-speaking countries since the 14th century.
How is the Pound Used Today: The pound plays a central role in both consumer life and various industries across the U.S. and the UK. From shopping to science, it's a standard unit for weight measurement when using the imperial system.
The Imperial ton, also known as the long ton, is a unit of mass used primarily in the United Kingdom and other Commonwealth countries. One imperial ton is equal to 2,240 pounds, or approximately 1,016.05 kilograms. This makes it heavier than both the US ton (short ton, 2,000 pounds) and the metric tonne (1,000 kilograms).
The imperial ton originated in the British Imperial system and dates back to times when goods were transported in large barrels or "tuns." These barrels typically held about 2,240 pounds of product—hence the origin of the long ton.
The unit was officially adopted as part of the British Imperial system in the 19th century. Though it's no longer widely used in trade or industry, it still appears in naval shipping, mining, and some historical references in the UK.
How Is the Imperial Ton Used: Today, the imperial ton is used less frequently due to the global adoption of the metric system. However, it remains relevant in:
1 lb = 0.000446 Imperial ton
Let’s say you want to convert 100 lb to Imperial ton.
Using the formula:
100 × 0.000446 = 0.045 Imperial ton
So, 100 lb is approximately 0.045 Imperial ton.
