Chronverter

## Description Chronverter is the essential tool for air gun and airsoft enthusiasts who need fast, accurate ballistics conversions on the field or at the range. Point your chronograph, enter the reading, and instantly see how your muzzle velocity translates across every common ammo weight — all in one clean, tactical interface. ### What It Does Feed Chronverter a single velocity reading and it calculates the equivalent speed and muzzle energy for every ammo weight you care about, using the industry-standard kinetic energy conversion formula (v₂ = v₁ × √(m₁/m₂)). No more mental math. No more spreadsheets. ### Key Features - **Instant multi-weight conversion** — See FPS, M/S, and Joules for all your ammo weights simultaneously in a clean, colour-coded table - **FPS & M/S support** — Switch between feet-per-second and metres-per-second with a single tap; input and output update instantly - **Reference-row highlighting** — The weight you measured is highlighted in amber so you can always see your baseline at a glance - **Custom ammo weights** — Add or remove weights to match your exact loadout; changes are saved automatically - **Persistent settings** — Your last-used ammo weight, velocity unit, and caliber are remembered between sessions - **Caliber tracking** — Log your barrel bore diameter in millimetres using the precision stepper or by typing directly - **Minimal, high-contrast UI** — Designed for bright outdoor conditions with a dark tactical theme and large, readable numbers ### Who It's For - Airsoft players verifying field limits before a game - Air gun shooters comparing pellet performance - Tech players and gun tuners optimising velocity for different ammo weights - Event referees or marshals performing quick field checks ### Formula Chronverter uses the conservation of kinetic energy principle to derive equivalent velocities: ``` v₂ = v₁ × √(m₁ / m₂) ``` Muzzle energy is calculated as: ``` E = ½ × m × v² ``` Results match the industry-standard ZeroOne airsoft calculator. --- No account required.
