Temperature conversion

Hi guys, i have a problem in solving my homework in mathcad 15.

The problem is when i try to add 2 temperatures because i want the result in Celcius and Mathcad work in Kelvin.

I'll show an example and and try to give me alternatives:

t1 = 10 C = 10 + 273 = 283 K

t2 = 20 C = 20 + 273 = 293 K

sum = t1 + t2

Mathcad will make:

sum = 283 + 293 = 576 K = 303 C (wrong)

I want:

sum = 10 + 20 = 30 C

1. Is it possible to modify the unit system from Mathcad and make it work with Celsius as default temperature unit?

2. If not, how can i resolve harder equations that contains summing of temperatures?

Re: Temperature conversion

In Mathcad 15, look under Help, Tutorials, Features In-Depth, Temperature and User-Defined Units.

Here will help you see that you need 10C + Delta 20C = 30C.

I hope this helps.

It is correct work with temperature and temperature different.
