How many kg is 239 pounds

Of course, the process was rudimentary and it wasn't entirely accurate, but it was a start. A first notable improvement of the measuring system appears in the Middle Ages, where apparently, people were quantifying their money by weighting them. The weighting device was a basic balance, which was using barley grains as counterweight.

This process was the most accurate of its time but still, a standard measurement was needed, in order to establish the true weight of an item in a fast and facile way. This is how the kilogram and pound appeared. Considering that in the late 's, there was no standard measurement unit, the merchants were constantly cheating their customers by altering the quantities.

The king ordered his specialists to create a standard weighting system, which cannot be altered and must be used by every merchant in the country. This is how the first decimal metric system appeared, and it was called a grave.

This system was designed as the mass of a liter of water, when it reaches its freezing point. This revolutionary metric system was extremely popular and soon after, what was known as a "grave", turned into a "gramme". The gramme was equal to the mass of 1 cm3 of water, near the freezing point. Even if it was accurate, the gram wasn't really practical for the commercial use and it had to be replaced with something bigger. That's when, they decided to multiply the weight of a gram and to create another measurement unit.

Definition of Pound: The pound shortened to lb. There have been different types of pounds throughout history. The one used in the US and other countries for weighing is the international avoirdupois pound. The abbreviation lbs. The pound belongs to the imperial measurement system, as opposed to the kilogram which belongs to the metric system. Use of the pound for weight is standard in the United States, as are the rest of the imperial system. A single kilogram is equivalent to grams.

This is the only unit in the metric system that has an SI prefix. You will find kilogram is also spelled as kilo or kilogramme. Kilograms, as do pounds, actually refer to the mass, not weight of an object. Weight is affected by gravity, while mass remains the same. But for simplicity and conventional use, kilograms and lbs.

If you need to know what lbs. It is not hard to convert lbs. Apart from the converter and the chart, you can do the conversion manually. To find out how many kilograms pounds is, multiply the pounds by 0. You can write this as x 0. One pound , the international avoirdupois pound, is legally defined as exactly 0.

The kilogram kg is the SI unit of mass. It is equal to the mass of the international prototype of the kilogram. This prototype is a platinum-iridium international prototype kept at the International Bureau of Weights and Measures. One kg is approximately equal to 2. To calculate a pound value to the corresponding value in kg, just multiply the quantity in pounds by 2.
