| From: | To: |
The conversion from miles per hour (mph) to meters per second (m/s) is a common unit conversion used in physics, engineering, and various scientific applications to translate speed measurements between imperial and metric systems.
The calculator uses the conversion formula:
Where:
Explanation: The conversion factor 0.44704 is derived from the relationship between miles and meters (1 mile = 1609.34 meters) and hours and seconds (1 hour = 3600 seconds).
Details: Accurate speed conversion is essential for international scientific research, engineering projects, transportation planning, and any application requiring consistent units across different measurement systems.
Tips: Enter speed in miles per hour. The value must be non-negative. The calculator will automatically convert to meters per second with precision to four decimal places.
Q1: Why is the conversion factor 0.44704?
A: This factor comes from the exact conversion: 1 mile = 1609.344 meters and 1 hour = 3600 seconds, so 1 mph = 1609.344/3600 = 0.44704 m/s.
Q2: When would I need to convert mph to m/s?
A: This conversion is commonly needed in physics experiments, engineering calculations, meteorological data analysis, and international transportation studies.
Q3: How accurate is this conversion?
A: The conversion is mathematically exact based on the defined relationship between miles and meters. The calculator provides results with precision to four decimal places.
Q4: Can I convert m/s back to mph?
A: Yes, to convert back, you would use the inverse: mph = m/s ÷ 0.44704 or mph = m/s × 2.23694.
Q5: Are there any limitations to this conversion?
A: This is a straightforward mathematical conversion without limitations, as long as the input values are valid numerical measurements.
