After helping with a local ham radio course, I realise how confusing some of
the units, symbols, & names are to new comers.
Here is a short look at the problem if the names/units/symbols get misused or
are unclear. They can normally be distinguished by the context & a thorough
knowledge of the subject concerned.
UNIT/
SYMBOL POSSIBLE MEANINGS
A Amperes, Area (a), Acceleration, ngstrom, Atto 10^-18, Attenuation,
Altitude, Argon.
B Magnetic Induction, Bars, Boron.
C Coulomb, Capacitance, øCentigrade/Celsius, Calories, Speed of Light,
Cycles, Carbon.
D Distance, Density, Dynes, Direction, Drag.
E Energy, Electric Fields, EMF, PD, Voltage, (e)rgs, Exa 10^18.
F Farad, Frequency Occurance, Force, Feet (Ft), Femto 10^-15, Fluorine.
G Force of Gravity, Giga 10^9, Conductance, (g)rams, Gauss, Gain.
H Henrys, Magnetic Field, Height, Hertz (Hz), Hydrogen.
I Current, Inductance, Inertia, Iodine, Imaginary in Maths.
J Jules, (j) imaginary in Electrical.
K øKelvin, (k)ilo 10^3, Potassium, Any Constant.
L Lumens (Lm), (l)itre, Lux (Lx) Inductance, Loss, Length, Lift.
M Mass, Moments, (m)etre, Mega 10^6, (m)illi 10^-3. Mile (Mi), Mo(1/ê).
N Newton, Nano 10^-9, Nitrogen.
O Örsteds, Oxygen.
P Power, Pressure, Pascal (Pa), (p)ico 10^-12, Peta 10^15, Phosphorus.
Q Charge, Resonant gain.
R Resistance, Radius, Reluctance.
S Siemens, (s)econds, Suseptance, Speed, Distance, Sulphur.
T Tesla, Tonne, Ton, Torque, Temperature, Network Type.
U Uranium, (U Signal Phase Axis). (U can be voltage says DK3UZ)
V Voltage, velocity, Volume, Vanadium, (signal Phase Axis).
W Watts, Work, Weight (Force), Tungsten.
X Reactance, Left Right Axis, Unknown.
Y Up Down Axis, Yttrium, (Luminance Signal).
Z AC Impedance, Far Near Axis, Network Type
æ Permeability, micro.
ê Ohms.
ã Pi, Network Type.
ë Delta, a Little bit.
,\ Lamda, wavelength.
(ohms View in code page 437)
Why Don't U send an interesting bul?
