To use a previous result, simply type the "=" character. It can be used anywhere in your next calculation, so it's pretty handy.

For example:

1/7 0.14

=*54 7.56

75-= 67.44

sqrt(=) 8.21

Also added Cranio's fine suggestion of using >> for conversions:

2ft+6in>>cm 76.20 (76 1/5)

You can also use " as " and " to " but you do need the spaces around 'em:

10m as ft 32.81 (32 38/47) (32' 9.7")

10mi to ft 52,800.00 (52,800' 0")
