Pressure conversion chart
To use this chart, simply place a straightedge so
that it intersects the known value and lies across
the center of the bullseye. Readings on all scales
will then be equivalent.
Ohms Law equation wheel
Using this wheel, you can calculate any one of the
following four basic factors of electricity, as long
as two of the others are known:
Power - Watts (W), shown as W
Current - Amperes (A), shown as A
Voltage - Volts (V), shown as E
Resistance - Ohms (W), shown as R
Choose an equation that will give you the value
that you need based on what values are already
known.
