Torque Formula:
| From: | To: |
The Watts to Torque conversion calculates the rotational force (torque) produced by an engine or motor based on its power output and angular velocity. This is essential for understanding vehicle performance characteristics.
The calculator uses the torque formula:
Where:
Explanation: This formula demonstrates the direct relationship between power, angular velocity, and torque. Higher power at the same angular velocity results in greater torque output.
Details: Torque is a crucial measurement in automotive engineering as it determines a vehicle's acceleration, towing capacity, and overall drivability. Understanding the relationship between power and torque helps in engine design and performance optimization.
Tips: Enter power in watts and angular velocity in radians per second. Both values must be positive numbers. For typical automotive applications, power is often converted from horsepower (1 hp = 745.7 W).
Q1: Why is torque important in cars?
A: Torque determines a vehicle's ability to accelerate and pull heavy loads. Higher torque at lower RPMs generally means better low-end acceleration and towing capability.
Q2: How do I convert horsepower to watts?
A: Multiply horsepower by 745.7 to get watts (1 hp = 745.7 W).
Q3: What is a typical torque value for passenger cars?
A: Most passenger cars produce between 100-400 N·m of torque, with performance vehicles often exceeding 500 N·m.
Q4: How does angular velocity relate to RPM?
A: Angular velocity in rad/s = RPM × π / 30. So 1000 RPM is approximately 104.72 rad/s.
Q5: Why use this calculation instead of direct torque measurement?
A: While direct measurement is more accurate, this calculation provides a quick estimation useful for design purposes, performance comparisons, and educational applications.
