Do you know about the `units` command?

I like `qalc` a lot:

    > 5 pounds to kg
    5 * pound = approx. 2.2679619 kg

    > x^2 + 8*x = 4
    ((x^2) + (8 * x)) = 4 = approx. x = 0.47213595 or x = -8.472136

And so on.

I didn't know about that! Strange interface, though -- why isn't the first response just "2.27kg"?

Because a kg goes into 5 lbs 2.2679619 times, and 5 lbs goes into 1 kg 0.44092452 times.

The first number is the one I want, pretty much 100% of the time, and I hardly ever need 8 digits of precision.

Units absolutely rocks. It can do quite complex calculations as well, and you can add to the units it knows.
