What am I doing wrong when I try to make this unit conversion?
I am trying to reconcile data that I have found in one publication (Allen 1969) with data that I found in another publication (George 2003) that synthesized this data. The
data is root respiration rate, it was originally measured at $27\ ^\circ…

How to express a mechanical force field in the units of electric fields?
Electrostatic fields have a unit $\frac{V}{m}$ (volts per meter) and the mechanical force fields (including gravitational field) have a unit $\frac{m}{s^2}$. If we exclude gravitational force from this question, as we know all mechanical forces are…

How to convert kWh/(m^3 multiplied by degrees celsius) to SI unit of Volumetric heat capacity?
We have a project at school about making more energy efficient buildings. We are using this software called Energy3D concord. In the window where you can edit the volumetric heat capacity, the units are $\frac{kWh}{m^3 C}$ as shown in the image. I…

Converting enthalpy from J/g to kJ/mol
On some books I found values of enthalpy in J/g, on other books in kJ/mol. How could I convert enthalpy from J/g to kJ/mol?
Thank you.

dynamic viscosity in the minute scale
The dynamic viscosity of air is $1.78\cdot 10^{-5}Pas = 1.78\cdot 10^{-5}\frac{kg}{ms}$. How do I convert this to the minute scale? I see a reason for multiplying the value with 60 (because of the $\frac{kg}{ms}$) or dividing it by 60 (because of…

Pi switching from 3.14 to 180°
The task goes as following: Calculate the amount of charge $Q$ of a unevenly charged semicircular ring with radiuses $a$ and $b$ if $\eta=\eta_0\sin\phi, 0<\phi<\pi$.
I started off by calculating the infinitesimally small surface $dS$ charged with…

Is there any intuition when using conversion factors inversely?
Suppose a car is traveling 5 m/sec. So after 3s it has traveled (3s)*(5m/s) = 15m. Of if the car has traveled 10m then it took (10m)/(5m/s) = 2s.
Suppose you used the conversion factor incorrectly, i.e. used the inverse. So for the latter example,…
