calculate the expansion length in SMath

Let's calculate the expansion length in SMath.
  

Linear expansion coefficient α= 0.0001
Temperature change Δt = 50 ℃
Member length L=40 m
Extension length Δl = α*Δt*L= 0.02 m

Calculate in SMath

  Δl = 0.1293 K m (where K is the absolute temperature and m is the meter)

When the temperature is entered, it can be seen that the temperature value is converted to absolute temperature and calculated.

  To obtain the result of Δl = α*Δt*L = 0.02m, the unit of Δt must be entered as Δ ℃, not ℃.

1*Δ°C = 1*K

 


Δl = 0.02 K m

 

The result is calculated well, but the unit looks strange because the absolute temperature K is included.

 

Finally, let's fix α= 0.0001/K.
