Fuel Pump Calculator
When you are trying to estimate fuel-pump flow capacity from horsepower, BSFC, density, and reserve margin, rough mental math can become surprisingly error-prone. The…
Commute Calculator
The Commute Calculator estimates monthly commuting cost and lets you compare a car or carpool scenario with public transport.
Compression Ratio Calculator
Small planning questions become easier when the assumptions are visible. The Compression Ratio Calculator is built to calculate an engine cylinder’s geometric compression ratio…
Compression Ratio to PSI Calculator
The Compression Ratio to PSI Calculator uses Pressure = X/Y × atmospheric pressure. Standard atmospheric pressure defaults to 14.7 psi. A 10:1 ratio gives…
Crosswind Calculator
When you are trying to separate an angled wind into crosswind and headwind/tailwind components, rough mental math can become surprisingly error-prone. The Crosswind Calculator…
Drive Time Calculator
The Drive Time Calculator combines travel time and fuel-cost planning in one workflow.
0-60 Calculator
Small planning questions become easier when the assumptions are visible. The 0-60 Calculator is built to compare a timed acceleration run on a common…
Boat Speed Calculator
The Boat Speed Calculator uses Crouch’s formula S = √(P/D) × C. Published C values are 150, 190, 210, 220, and 230 for the…
Boost Horsepower Calculator
When you are trying to see the simplified power increase implied by a boost-pressure target, rough mental math can become surprisingly error-prone. The Boost…
