Speed Conversion Formulas:
| From: | To: |
Speed conversion involves transforming speed measurements from one unit system to another. This calculator specifically converts between miles per hour (mph) and meters per second (m/s), or calculates speed from rotational measurements (rpm) and circumference.
The calculator uses two conversion formulas:
Where:
Explanation: The first formula converts directly from mph to m/s using the conversion factor 2.23694. The second formula calculates linear speed from rotational speed and wheel/tire circumference.
Details: Accurate speed conversion is essential in various fields including automotive engineering, sports science, physics calculations, and international unit standardization. Converting between different speed units allows for consistent measurements across different systems and applications.
Tips: Enter either mph value OR both rpm and circumference values. The calculator will prioritize mph conversion if both inputs are provided. All values must be positive numbers.
Q1: Why convert mph to m/s?
A: M/s is the SI unit for speed and is commonly used in scientific calculations, while mph is more common in everyday usage in some countries.
Q2: What is the conversion factor 2.23694?
A: This factor represents how many mph equal 1 m/s (1 m/s = 2.23694 mph).
Q3: How do I measure circumference for rpm conversion?
A: Measure the distance around the wheel or rotating object in meters, or calculate from diameter (circumference = π × diameter).
Q4: Can I use this for any rotating object?
A: Yes, as long as you have accurate rpm and circumference measurements for the specific object.
Q5: Which input method is more accurate?
A: Both methods are mathematically precise. The choice depends on which measurements you have available and the specific application context.
