A calculator for PCP (pre-charged pneumatic) air rifle shooters. Find out how many complete and partial recharges a scuba/dive cylinder can give your rifle — and how much air is wasted in the fill hose on every disconnect.
Features:
• Input in liters or cc, pressure in bar or PSI.
• Real-gas model (compressibility factor) for better accuracy at high pressure.
• Complete recharges + partial recharge and the cylinder's final pressure.
• Hose waste expressed as a fraction of one full recharge.
• Pressure decay curve chart across recharges.
• 100% offline, no sign-up.
