Conversion Tables

Resistance
Opposition to current flow. Basic unit is the ohm (Ω)
1 kilohm ‐ kΩ1,000 or 1x103 ohms
1 Megohm ‐ MΩ1,000,000 or 1x106 ohms
Voltage
Electromotive force. Basic unit is the volt (V)
1 millivolt ‐ mV1/1,000 or 1x10-3 volt
1 microvolt ‐ μV1/1,000,000 or 1x10-6 volt
Current
Movement of electricity. Basic unit is the ampere (A)
1 milliampere ‐ mA1/1,000 or 1x10-3 ampere
1 microampere ‐ µA1/1,000,000 or 1x10-6 ampere
Frequency
Number of cycles per second. Basic unit is the hertz (Hz)
1 kilohertz ‐ kHz1,000 or 1x103 hertz
1 Megahertz ‐ MHz1,000,000 or 1x106 hertz
1 Gigahertz ‐ GHz1,000,000,000 or 1x109 hertz
Frequency
Basic unit is the second (s)
1 millisecond ‐ ms1/1,000 or 1x10-3 second
1 microsecond ‐ μs1/1,000,000 or 1x10-6 second
1 nanosecond ‐ ns1/1,000,000,000 or 1x10-9 second
Operating Life for Capacitors
Where operating life is given at a certain temperature, for every drop of 10°C life expectancy will double.
If life expectancy is 1,000 hours at 105°C
this would double to 2,000 hours at 95°C
and double again to 4,000 hours at 85°C
