pounds to kilos
IŽd like to know how I can convert pounds to kilograms. For instance how many kilograms equal 100 lbs. And vice versa.

IŽd also like to know how to convert, miles to kilameters, and inches to centimiters.

1 pound equals 0.4536 kg (or 453.6 grams). So multiply pounds with 0.4536 to get kilograms.

One (imperial) mile equals 1.6093 km (or 1609.3 metres).
One (imperial) inch equals 2.54 cm (or 0.0254 metres).

You can view all the metric to imperial stuff over at http://convert.french-property.co.uk/ and many other websites as well.

Google will actually perform unit conversions like this.

Just type "100lbs in kg" and hit search

However, just to prove how anal I am... :o

You all are aware, of course that there IS no true conversion between lbs and kg? I teach unit conversions in my Physics classes and I've always had a hard time teaching what units go with what physical quantities thanks to the European convention of measuring weight in "kilograms."

For the record, the metric (i.e. MKS) unit for weight is the "Newton," not the kilogram, which measures mass. I usually take the standard (if there is one!) English unit for mass as being the "slug." So we convert pounds to Newtons and slugs to kilograms.

BTW: My favorite unit is the "furlong/fortnight."

I'll stop ranting now...Thank you. :D

Best remembered as the weight of an apple is about 1 Newton :D

Not that the imperial/customary system of was above using the pound
as a unit of force and mass. I suppose that is to avoid the terror associated
with killer Slugs :D
