Nitrous Bottle Consumption Calculator
Use scale readings to measure nitrous used, consumption per second, and estimated passes remaining. Weigh the same bottle assembly each time.

Predictions assume future passes use the same amount as the measured passes. Purging, leaks and venting between weighings are included in measured consumption. Weight estimates do not guarantee liquid delivery, stable pressure or consistent performance. Tare must include the same valve and hardware as the scale readings. Changing units relabels entries; enter corresponding weights in the selected unit.
Formula and assumptions
Used = before − after. Rate = used ÷ total activation seconds. Average per pass = used ÷ measured passes. Usable remaining = max(0, after − tare − reserve). Complete estimated passes = floor(usable remaining ÷ average per pass).
