I've used mathcad previously and have switched to smath. Smath has seemed like a very nice program so far but i've been struggling with its temperature units. See image below.




am I missing something? Almost seems like the answer is actually in kelvin?

Hello,

The SMath's answer is right. The same answer will be in Mathcad too.

Just browse the Forum and find something like this Temperature-units-handling

Celsius is a relative temperature scale, Kelvin is an absolute one: 0C+0C=273.15K+273.15K=546.3K=273.15C
