Torque Formula:
| From: | To: |
The torque formula calculates rotational force from power and RPM. It provides a fundamental relationship between these mechanical properties, essential for understanding engine and motor performance.
The calculator uses the torque formula:
Where:
Explanation: The formula demonstrates the inverse relationship between torque and RPM for a given power output. The constant 5252 comes from the conversion between horsepower, foot-pounds, and minutes.
Details: Torque calculation is crucial for evaluating engine performance, designing mechanical systems, and understanding the relationship between power output and rotational speed in various applications.
Tips: Enter power in horsepower (HP) and RPM in revolutions per minute. All values must be valid (power > 0, RPM > 0).
Q1: Why is 5252 used in the formula?
A: 5252 is a conversion constant derived from the relationship between horsepower (550 ft-lb/sec) and RPM (revolutions per minute).
Q2: What are typical torque values for engines?
A: Torque values vary significantly by engine type and size. Automotive engines typically produce 100-500 lb-ft of torque, while industrial engines can produce much higher values.
Q3: How does torque relate to vehicle performance?
A: Higher torque generally provides better acceleration and towing capacity, while higher RPM capabilities relate to maximum speed potential.
Q4: Can this formula be used for electric motors?
A: Yes, the formula applies to any rotating mechanical system, though electric motors often have different torque characteristics across their RPM range.
Q5: What units does this calculation use?
A: This calculator uses horsepower for power and lb-ft for torque. For metric units, different conversion factors would be needed.
