The horsepower and torque figures that automotive manufacturers advertise for their vehicles are always crank numbers. Crank numbers are the HP and Torque values as measured at the engine. To see these values, an engine must be connected to an Read more…
One SAE hp is the ability to lift 33,000 lbs one foot in one minute. One DIN hp (DIN stands for “Deutsche Industrie Normen” or “German Industrial Standard”) is the ability to lift 450000 kg one cm in one minute. Read more…
What is the horsepower of my boat’s motor? The horsepower is usually painted in large numbers on the motor itself. Sometimes the horsepower is part of the model code. If you are unsure check the manual or ask your repairer. Read more…
Metric horsepower is 75 m kgf/s, which equals 735.49875 watts. On the other hand, imperial horsepower is exactly 746 watts. While watts are the SI unit of measurement for power, the amount of power generated by most large machines is Read more…
[3] In the US customary system of measurement, which is non-coherent, the unit of power is the horsepower, which is defined as 550 foot-pounds per second (the pound in this context being the pound-force); similarly the gallon is not equal Read more…
1972. After 1972, an engines power output was quoted as “net horsepower,” and just like “gross horsepower,” it was measured at the crankshaft, so it too does not take into account drivetrain losses. When did net horsepower come out? In Read more…
The Standard Association of Australia (SAA) adopted the Systeme International d’Unites (SI) in 1977 which determines the unit of power is best expressed as a kilowatt. One kilowatt is equivalent to 1.34 horsepower. To determine what a kilowatt is from Read more…
This dynamometer is able to put on a load on the outboard motor engine and measure the power it can produce. Once the amount of power is known to us we can determine the torque force. To calculate the horsepower Read more…
Horsepower Output (kW). Usually labeled as HP or kW, this is the measure of the motors ability to deliver the torque required for the load at a rated speed. hp = 0.746 x kW; conversely, kW =1.34 x hp. How Read more…
A power level of 1 hp is approximately equivalent to 746 watts (W) or 0.746 kilowatts (kW). To convert from horsepower to watts, multiply by 746. To convert from watts to horsepower, multiply by 0.00134. What is the electrical equivalent Read more…
