Aviation Fuel Converter3.4.1 - App Store

Written by a pilot for pilots, flight crews, refuelers, and line personnel worldwide. Aviation Fuel Converter provides instant, high-precision fuel conversions between volume and weight across global aviation fuels and international measurement units.

All that is required is to enter your fuel remaining and fuel desired-the app instantly calculates the exact fuel to add across US Gallons, Pounds, Liters, Kilograms, and Imperial Gallons.

Whether you are calculating turnaround uplifts, adjusting for temperature density on a hot ramp, or planning symmetrical multi-tank distribution, Aviation Fuel Converter delivers flight-tested accuracy in seconds.

KEY FEATURES & CAPABILITIES
==================================================

. COMPLETE VOLUME & WEIGHT CONVERSIONS
Instantly convert between all 5 international aviation units:
- US Gallons (gals)
- Pounds (lbs)
- Liters (ltrs)
- Kilograms (kgs)
- Imperial Gallons (Imp gals)

. GLOBAL AVIATION FUELS SUPPORTED
Pre-loaded with official ASTM baseline densities (@ 15°C / 59°F) and customizable Specific Gravity (SG) overrides:
- Jet A & Jet A-1 (6.70 lbs/gal | 0.804 kg/L)
- 100LL AvGas (6.00 lbs/gal | 0.720 kg/L)
- Sustainable Aviation Fuel / SAF (6.42 lbs/gal | 0.769 kg/L)
- Mogas / Auto Gas (6.10 lbs/gal | 0.730 kg/L)
- TS-1 Kerosene (6.48 lbs/gal | 0.776 kg/L)

. ASTM D1250 TEMPERATURE DENSITY CORRECTION
Aviation fuel expands in heat and contracts in cold. Our ASTM D1250 thermal engine independently compensates for:
- Fuel in Tank Temp: Adjust for sun-baked wings or high-altitude cold soaking.
- Fuel To Be Added Temp: Adjust for ambient temperature of delivered fuel.
- Supports both Celsius (°C) and Fahrenheit (°F) with sub-zero negative inputs.

. AIRCRAFT PROFILES & SYMMETRICAL TANK LOADING
Save named aircraft profiles (King Air, Citation, Bell 407, Skyhawk, etc.) with custom tank capacities and fill priorities:
- Symmetrical Multi-Tank Loading: Automated algorithm balances fuel across main, aux, tip, and center tanks.
- Dual-Unit Dispensing: Read your gauges in native units (lbs/gal) while calculating exact refueler orders in liters or gallons.
- Imbalance Adjustments: Set initial fuel per tank with automatic symmetrical distribution of remaining uplift.
- One-Tap Clipboard Export: Copy clean loading manifests and fuel slips directly to clipboard.

. 5 COCKPIT FLIGHT DECK THEMES
Engineered for real-world cockpit lighting environments:
- Daylight High Contrast: Glare-resistant for direct midday sunlight.
- OLED Dark Cockpit: True black (#000000) for night flight battery and vision preservation.
- Night Vision Red (NVG Mode): Monochromatic aviation red preserving dark adaptation.
- Avionics Glass Cockpit: Instrument slate and cyan glow matching modern glass PFDs.
- System Auto: Automatically tracks host device settings.

. 11 GLOBAL FLIGHT LANGUAGES
Full native localization in English, Spanish, French, Portuguese, German, Japanese, Chinese, Arabic (RTL layout), Russian, Italian, and Hindi.

. 100% OFFLINE & PRIVACY FIRST
No internet connection required. Zero ads, zero trackers, zero data collection. All calculations run strictly on-device for dependable remote airfield operations.

FLIGHT SAFETY NOTICE
==================================================
Always cross-check fuel calculations with your official Aircraft Flight Manual (AFM) / Pilot's Operating Handbook (POH) and weight & balance manifest prior to flight dispatch.
