#10 Convert to interface

[Anonymous]

Calculate should feature a convert to function build in the interface of the program (i.e. expression line)
for example having an expression like
16kg×8m/24s^3:Watt
should output the answer and then convert it to watts, so that if 16kg×8m/24s^3:Watt:Joules, should output the answer, converted to watts, and then converted to joules (all 3 answer are displayed)

This later is just a suggestion but it will really be appreciated if a build right in the syntax conversion is possible
