A bunch of things™ that I found important enough to calculate/have access to/include in places where it wouldn't go otherwise
Stator Volume
Motor Size:
Result:
mm³
The motor stator size is listed as xxyy, with the xx being the
width, and yy being the height. A 2207 motor will have a stator 22mm wide,
and 7mm high
The calculation to get the stator volume is for a simple cylinder:
π × r2 × h

dBm <―> mW
dBm
mW
dBm is a unit of power measurement. It is a logarithmic unit (unlike Watts), and is used to compare the power of different signals.
Given power in dBm,
the calculation to get the power in mW is
mW = 10(dBm/10)
Given power in mW,
the calculation to get the power in dBm is
dBm = 10 × (log10 mW)
LiPo Wh
cell
mAh
Result:
Wh
Wh is a unit of energy measurement. It denotes the power over time, and is
used to compare the energy capacity of different batteries.
The calculation to get the Wh of a LiPo is:
Ah × 3.7 (nominal voltage) × # of cells
