Engineer's Unit Converter vs BrennerCalc

A unit converter built for engineering work rather than for the kitchen. Thirty-two categories, from the everyday ones to the specialist tables you normally go looking for in a handbook: AWG wire gauge, tons of refrigeration, viscosity, water hardness, radiation dose, moment of inertia. EVERY CATEGORY, ALL FREE Length, Area, Pressure/Stress, Mass/Weight, Energy/Work, Power, Force, Torque, Volume, Temperature, Time, Speed, Angle, Data, Frequency, Fuel Economy, Density, Flow, Viscosity, Acceleration, Electric Current, Voltage, Resistance, Electric Charge, Magnetic Flux Density, HVAC Cooling, Water Hardness, Radiation Activity, Radiation Dose, Radiation Equivalent Dose, Moment of Inertia, Wire Gauge. No unlocks, no ad to watch first, no timer. Every category above is open the moment you install. ENGINEERING TOOLS An expression calculator that accepts arithmetic, fractions and scientific notation, so you can type 3/8 or 1.2e-3 straight into the field. An HVAC sizing helper that turns tons of refrigeration into BTU/h, kW and rule-of-thumb airflow. Reference tables for physical constants, thermocouple types and hardness scales. BUILT FOR THE JOB Works fully offline, so it does not care about signal on site. Reads decimal commas and points the way your region writes them. Pin the units you use, hide the ones you never touch, and reorder the rest. Add your own units with a conversion factor. Every conversion is kept in a searchable history you can tap to reuse. No account, no sign-in, no data leaves the device.

BrennerCalc is a compact calculation tool for heating, HVAC and service technicians. The app focuses on fast calculations without accounts, advertising or unnecessary distractions. Features: - Oil burner: account for nozzle size and pump pressure and calculate oil flow and output - Reverse calculation: convert desired output into required nozzle size - Gas: convert volume flow and heating value into burner input/output - Hydronics: calculate required water flow from heat output and temperature difference - Results in l/h, l/min, m³/h and kW - German and English - Works offline BrennerCalc Pro permanently unlocks the additional gas and hydronic calculators with a one-time in-app purchase. Important: BrennerCalc is a calculation aid for trained professionals. Manufacturer specifications, applicable standards, commissioning measurements and combustion analysis always take precedence.
