Every classic pilot calculator, polished and consistent. - Conversions. Length, speed, temperature, pressure, weight, volume, fuel mass. Drag any value to scrub it. - Apple Watch app. Six elegant conversion canvases (altitude, vertical speed, distance, speed, temperature, pressure). Digital Crown to scrub, tap to flip the active unit. DESIGNED FOR THE WHOLE WORLD - Multiple fuel types: Avgas 100LL, Jet A, Mogas, UL94, SAF. Density shown in lb per gal or kg per L depending on your selected unit. - Pick weight in lb or kg, distance in inches or cm, fuel as gallons, liters, kilograms, or pounds, all independently. No "imperial vs metric" toggle that fights your AFM. - Fuel price, computed per gallon, liter, kg, or lb using the active density. - Everything runs offline. No account. No subscription. No ads. LetzFly Computer was built by pilots, for pilots. If your next preflight feels lighter, we did our job. Disclaimer: LetzFly Computer is a planning aid, not a primary flight instrument. Always cross-check weight and balance results against the aircraft's current weighing sheet before flight.
