A collection of various calculators and other stuff™

A bunch of things™ that I found important enough to calculate/have access to/include in places where it wouldn't go otherwise

Calculators

Stator Volume

Motor Size:

Result:

NaN

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:

0

Wh

HV LiPo

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
