I'm not sure if it was mentioned here, but you could also use Google's calculator if you are online. Try the following in the Google search window: 10A in biot 1 inch in points There are a lot of others (though not ell's or calibres!), maybe they'd add those if you let them know they're missing :-) The biggest omission is that they don't tell you exactly what it can do! I presume that is to stop their competitors from duplicating it easily!
