How do you make a low pass filter into a high pass filter?

Lowpass to Highpass

The lowpass prototype is converted to highpass filter by scaling by 1/s in the transfer function. In practice, this amounts to capacitors becoming inductors with a value 1/C, and inductors becoming capacitors with a value of 1/L for passive designs.
