terminology
Peak to valley means the highest point of the signal to the lowest point. It's a little like peak-peak except that it implies a DC bias so that the "negative peaks" don't cross 0V, so valley is a better name for them. mm/µv means millimetres per microvolt, or metres per millivolt.

Peak Voltage (V P ) Calculator
The Peak Voltage calculator calculates the peak Voltage value from either the peak-to-peak voltage, the RMS voltage, or the average voltage. It calculates the peak Voltage based on the above formulas for each respectively. To compute VP from the peak-to-peak voltage, the peak-to-peak voltage is multiplied by 0.5.

Baseline Noise: Measuring Peak-to-Peak Noise
Peak-to-peak noise, measured in a classical sense, is simply the highest noise point across the measured region minus the lowest noise point. You can imagine that if this were a gradient chromatogram or if there was significant drift over the measured region, your noise calculation could quite simply equal the drift calculation (Figure 1).
