HP Prime and units? - Ohveli - 01-03-2019 09:44 PM
Hi,
I've been considering purchasing the HP Prime and decided to test the HP Prime Lite Android app beforehand. I've encountered some oddities in how the app handles units.
For example:
2.3_m/s^2 * 3_s does give the answer as 6.9_m/s
But 2.3_m/s^2 * 3_mn gives the answer as 6.9_(m*mn)/s^2
In fact it would seem that any unit of time other then seconds results in similar odd units.
Also 5_A * 8_V gives 40_(A*V) rather then 40_W and attempts at calculating kinetic energy, force exerted by pressure and several others give similarly odd answers.
Is this just the app or does the calculator give the same odd answers?

Follow the above with: USIMPLIFY(Ans)

Yes, it is generally a bad idea to attempt to convert complex units into other forms except on demand because there are so many possibilities.
