Although many people in the United States think of weight in terms of pounds, many healthcare facilities record weight in kilograms. Although using an online convertor is quick and easy, it is helpful to know how to do the conversion so that you can compute a weight without the aid of the Internet. For simplicity's sake, I have rounded the conversion number to the nearest 100th. If you need a more exact number, use 0.45359237 instead of 0.45.

Here is the conversion for lb to kg: 1 lb = 0.45 kg

In order to obtain kilograms if you have a weight in pounds, simply multiply the number by 0.45.

Below are a few examples:

Weight in Pounds	Multiply by	Weight in Kilograms
10	0.45	4.5
75	0.45	33.75
130	0.45	58.5
200	0.45	90
275	0.45	123.75
1000	0.45	450
