In practice smaller units are used such as the microfarad (abbreviated µF), nanofarad (nF) and picofarad (pF).
the nonpolarized capacitors, of low value nanofarad or microfarad are primarily of technology mylar or ceramics

Values of 0.001 µF and above were stated in microfarads (µF, or often mF); lower values were stated in micro-microfarads (µµF, now called picofarads, pF).
Using a nomograph: Draw a straight line from your chosen 30 kHz frequency (purple line) through your chosen 100 nanofarad capacitor value and carry the line on as far as the (blue) inductance line as shown above.
As the voltage builds up on the 68 nanofarad capacitor it eventually reaches the point at which it triggers the triac, which then switches on and remains on until the mains voltage drops down to zero again.
