    You calculate the KHz by dividing by the time between the peaks of the waveform.  A good digital oscilloscope will calculate it for you by using the on-screen measurement cursors. Some instruments have waveform capture and download capability. The issue with ultrasound (or any sound) measurement is triggering on the correct wave.  There are direct waves from the source to the microphone, and there are reflected waves from walls, floor, ceiling, and other objects. All these waves will have different waveform characteristics.  If you want to measure frequency directly, then use a spectrum analyzer.
