By converting pounds to kilograms, and then converting cubic feet to cubic meters.

One pound is 0.454 kg, and one cubic meter is 10.76 Ft². Using this info:
Code: Select all
lb | 0.454 kg | 10.76 ft²
---|----------|---------
ft²|    lb    |      m²

We can now cancel out ft² over ft² and lb over lb, giving us:

0.454 kg · 10.76
-------------------- = 4.89 kg/m²


so, 1 lb/ft² = 4.89 kg/m²

Is there an easier way to convert this stuff without doing a conversion table? There has to be a shortcut, I just haven't been able to find one. Calculators only convert between like units, and some simpler combinations like miles/hr. any ideas?

Sorry if I wasn't more clear when I went through the exersize above. The calculation that I showed you tells you what the shortcut is. One lb/ft² = 4.89 kg/m².

You can only have a shortcut if you know how to get to where your going in the first place. Now that you know how we got there, here's the shortcut:

Take your value in lb/ft² and multiply it by 4.89. That will give you the answer in kg/m². Or take kg/m² and divide it by 4.89 to get back to lb/ft².

Yeah, this Kg/m^2, but how do you get Kg/m^3?

There is an error in the units being converted. It should be

1 lb/ft^3 x 0.45359 kg/lb x (1 ft/0.3048 m)^3 =

16.018 kg/m^3

I'm surprised at how many web sites supposedly converting pounds to kilograms don't use an accurate conversion. I wonder how much that translates to in excess shipping costs?
