What Is This Tool?
This converter transforms values of angular velocity measured in revolutions per hour into radians per second, enabling the use of standard SI units for precise engineering and scientific purposes.
How to Use This Tool?
- Enter the angular velocity value in revolutions per hour (r/h).
- Select the input unit as revolution/hour [r/h].
- Choose radian/second [rad/s] as the output unit.
- Click the convert button to get the equivalent rad/s value.
Key Features
- Converts revolution/hour [r/h] values into radian/second [rad/s].
- Utilizes the exact conversion rate based on 1 r/h = 0.0017453293 rad/s.
- Supports applications in engineering, robotics, astronomy, and more.
- Easy to use browser-based conversion tool.
Examples
- Convert 5 r/h: 5 × 0.0017453293 rad/s = 0.0087266465 rad/s.
- Convert 10 r/h: 10 × 0.0017453293 rad/s = 0.017453293 rad/s.
Common Use Cases
- Express slow rotational speeds for solar trackers or antenna mounts in SI units.
- Monitor rotation rates of slow industrial equipment like rotary kilns and large mixers.
- Calculate rotational rates for planetary or satellite motion in astronomy and geoscience.
- Integrate angular velocity data into engineering analyses involving torque and frequency.
Tips & Best Practices
- Use this conversion to represent slow rotations with accurate SI units.
- Apply the tool for engineering tasks requiring angular velocity in rad/s.
- Confirm unit selections before converting to ensure correct results.
- Avoid using this unit for high-speed rotations where other units may be more suitable.
Limitations
- Revolution/hour reflects slow rotation rates, so it is less practical for fast spinning objects.
- The conversion depends on the exact 2π factor; approximations may reduce precision.
- Not ideal for applications requiring rapid velocity changes or high-speed measurements.
Frequently Asked Questions
- What does revolution per hour [r/h] measure?
- It measures angular velocity indicating how many full revolutions occur in one hour, suitable for slow rotation rates.
- Why convert r/h to rad/s?
- Converting to rad/s aligns with the SI unit system, enabling integration with engineering calculations involving torque, frequency, and dynamics.
- Is revolution/hour useful for fast rotations?
- No, revolution/hour is intended for slow rotational speeds and is less practical for fast rotations where rad/s or rpm are preferred.
Key Terminology
- Revolution/hour [r/h]
- A unit of angular velocity representing the number of complete 360° rotations occurring each hour, used for slow rotational speeds.
- Radian/second [rad/s]
- An SI derived unit measuring angular velocity as the angle in radians swept per second, widely used in physics and engineering.
- Angular velocity
- The rate at which an object rotates or revolves around an axis, often measured in radians per second or revolutions per unit time.
