Assume voltage or current waveform frequency = 60 cycles/sec or 60 Hz

cycle =
millisecond

° degree =
milliseconds

° degree =
cycle

Assume voltage or current waveform frequency = 50 cycles/sec or 50 Hz

cycle =
millisecond

° degree =
millisecond

° degree =
cycle

**Reference frequency is 100,000 Hz or 100 kHz**

cycle =
microsecond

10 microsecond = 10µsec = 10 x 10^{-6} second =10 e^{-6} second = 0.000010 sec

**Reference frequency is 50 MHz**

cycle =
nanosecond

20 nanosecond = 20 nsec = 20 x 10^{-9} second =20 e^{-9} second = 0.000000020 sec

For 60 Hz

1 cycle * sec /60 cycles = 0.0166667 seconds = 16.667 milliseconds

360 electrical degree = 1 cycle

1 ° degree = 1/360 cycle = 0.002778 cycle

For 50 Hz

1 cycle * sec /50 cycles = 0.02 seconds = 20 milliseconds
