I must agree that libraries are a key factor. I recently developed a site with.Net and I am headed back to Java for better libraries---data structures, numerical support, frameworks, etc.
I'll plug my site, http://www.knowledgedoor.com/, which has some unique unit conversion capabilities. We can take mathematical expressions with embedded units and convert them to units you specify (like Google) but we can also go directly to metric units. That is, you can put in a mathematical expression and we will suggest metric units for it. We can also take two mathematical expressions and check for unit consistency or extract their base units and dimensions. We return detailed error messages in response to conversion problems and warn you when you use units with different variations (like the pint, calorie, etc.). We've also got some great base conversion of integer and fractional numbers.

Or, 604.67 degrees Rankine, or 2.3710484813e-30 of the Planck temperature :-) Just thought I'd plug my site http://www.knowledgedoor.com/.
