Calculators
Unit converters and load calculators for trucks and buses. Every factor comes from NIST or from the carriers named on each page, and each page shows the formula.
- kW ↔ PS ↔ hpkW to hp and PS converter: kilowatts and both horsepowersConvert engine power between kilowatts, metric horsepower (PS, CV, л.с.) and the 550 ft·lbf/s horsepower (hp) with NIST's factors: 1 PS = 0.7354988 kW, 1 hp = 0.7456999 kW.
- Nm ↔ lb-ft ↔ kgf·mNm to lb-ft and kgf·m converter: engine torque unitsConvert engine torque between newton metres, pound-force feet (lb-ft) and kilogram-force metres (kgf·m) with NIST's factors: 1 lbf·ft = 1.355818 Nm, 1 kgf·m = 9.80665 Nm.
- l/100 km ↔ mpgmpg to l/100 km: fuel consumption converter and trip fuel costConvert fuel consumption between litres per 100 km, km per litre and US or UK miles per gallon, and work out the fuel and cost of a trip. Formulas from NIST's gallon and mile.
- mi · mph · gal · lbMiles, mph, gallons and pounds to metric: unit converter for trucksConvert miles and km, mph and km/h, US and imperial gallons and litres, pounds, short tons and tonnes, with NIST's factors. Useful for US and UK truck data sheets.
- Loading metres (LDM)Loading metre (LDM) calculator: pallets, stacking and trailer lengthWork out loading metres for Euro, industrial and other pallets, with or without stacking: LDM = length × width ÷ 2.4 m, as Gebrüder Weiss and Koch International calculate it.
- Tyre load indexTyre load index and speed symbol calculator: kg per tyre and per axleRead a tyre's load index and speed symbol as kilograms per tyre and per axle, single or dual, and find the lowest load index an axle load needs. Table from UNECE Regulation 54.
