Encoder resolution (PPR ↔ degrees per pulse)
Convert between encoder Pulses Per Revolution (PPR), Cycles Per Revolution (CPR), and angular resolution down to arcseconds.
Heat Index Feels-Like
Assess felt air heat indexes using ambient temperature and relative humidity thresholds.
Voltage Divider Designer
Calculate output voltage, resistor ratios, and locate standard E24 resistor values for divider networks.
Displacement tonnage ↔ cubic meters — ship buoyancy
Convert ship displacement tonnage to submerged volume (m³) and buoyancy force. Choose between freshwater and saltwater standards.
Morse code ↔ NATO phonetic — dual encoding
Convert raw text into international Morse Code (DITs and DAHs) and official NATO spelling phonetics synchronously.
AUTOMOTIVE Utilities
Choose a specialized option to begin instant real-time conversion.
Tire size decoder — 205/55R16 ↔ diameter ↔ width ↔ aspect
Decode metric tire specs to calculate sidewall height, total diameter, circumference, and compare speedometer error against a secondary size.
Gear ratio ↔ final drive speed — RPM at given speed
Calculate vehicle road speed or engine RPM based on transmission gear ratios, final drive axle ratio, and tire dimensions.
Engine displacement — cc ↔ cubic inches ↔ liters
Convert and calculate total engine volume in cc, cubic inches, and liters using cylinder bore, piston stroke, and cylinder count.
Compression ratio — bore + stroke + head volume
Calculate static compression ratios from cylinder bore, stroke, head chamber volume, gasket thickness, deck clearance, and dome/dish specs.
Injector duty cycle — fuel demand ↔ injector size
Match fuel injector sizes (cc/min or lb/hr) with horsepower targets, number of cylinders, and Brake Specific Fuel Consumption (BSFC) targets.
Spring rate — lb/in ↔ N/mm — suspension setup
Convert suspension coil spring stiffness between lb/in and N/mm. Estimate coil spring rates using wire diameter, coil diameter, and active counts.
Camber angle — mm of offset ↔ degrees
Convert alignment offset deflection in millimeters to degrees of camber angle based on rim diameter, or vice versa.
