History of Lbs and Kg
The pound has a rich history dating back to ancient Rome, where it was known as the “libra.” Over time, the pound evolved into various standards, with different countries adopting their own versions. The international standard pound, defined in 1959, is based on the mass of a platinum-iridium cylinder kept at the International Bureau of Weights and Measures in Paris, France.
The kilogram, on the other hand, is a relatively modern unit, established in 1799 during the French Revolution. It was originally defined as the mass of one liter of water at 4 degrees Celsius. However, in 1889, the kilogram was redefined as the mass of a specific platinum-iridium cylinder, known as the International Prototype Kilogram (IPK). In 2019, the kilogram was redefined again, this time based on fundamental physical constants, ensuring its stability and accuracy.
