GS-HU — Aftermarket Head-Unit Deutsch Plug Wiring Standard
Public technical standard, working draft Rev 0.2 for a fixed vehicle-side Deutsch DT/DTM socket language for aftermarket head units. Cavity maps remain schematic until verified on stock; pin functions are the interface. May be copied with attribution. The attached PDF is the authoritative 8-page layout. Supersedes withdrawn internal 12-way/XTRA Rev 0.1.
Automotive Refrigerant — Saturation P↔T
Saturation (boiling/condensing) lookup both ways with interpolation. Fluids: R134a, R1234yf, R12 legacy, R290, R600a, and HyChill Minus 30 (manufacturer chart). Saturation ≠ normal running pressure; this is not a charge recipe—assume trade understanding. Minus 30 ≠ pure R290 or R600a; A3 flammable—use approved equipment and follow SDS, recovery, licensing and WHS requirements.

Calibration of the Xgard Type 5 gas detector.
Ethanol water fraction per temperature and presure
Homebrew Wash Sugar per Volume and ABV Results Calculator.
Ideal Gas Standard Volume Conversion Calculator
Calculates the standard volumetric flow rate from actual flowing conditions using absolute pressure and absolute temperature based on the Ideal Gas Law.
Orifice Plate Pressure Correction Factor Calculator
Calculates the pressure correction factor for a differential pressure flow device (such as an orifice plate) when the flowing pressure differs from the design pressure. Pressures must be entered as absolute pressure (pressure referenced to a perfect vacuum).
Buoyancy & Floatation Calculator
Calculates buoyant force, required displacement volume, and float/sink condition based on Archimedes’ Principle. Useful for marine design, flotation devices, tanks, pontoons, and load analysis.
Flange Table Identification
Steam Table
Fuel Economy Calculator
Calculates fuel economy in litres per 100 kilometres and kilometres per litre based on distance and fuel usage.
