How It Works
Converting from miles per hour (mph) to meters per second (m/s) is a common speed conversion that bridges the imperial system (miles) with the SI system (meters). This conversion is particularly useful in scientific and engineering contexts.
Conversion Formula:
1 mile per hour = 0.44704 meters per second
To convert miles per hour to meters per second, multiply the miles per hour value by 0.44704:
Meters per Second = Miles per Hour × 0.44704
Why is the factor 0.44704?
The conversion factor 0.44704 comes from:
- 1 mile = 1609.344 meters
- 1 hour = 3600 seconds
So, 1 mph = 1609.344 / 3600 = 0.44704 m/s
Example Calculation:
To convert 55 miles per hour to meters per second:
Meters per Second = 55 mph × 0.44704 = 24.5872 m/s
Our converter handles this calculation automatically and provides results with up to 9 decimal places for precision. It also formats the result to remove unnecessary trailing zeros for better readability.
Frequently Asked Questions
What is a mile per hour?
A mile per hour (mph) is a unit of speed in the imperial and US customary systems, representing the number of miles traveled in one hour. It’s commonly used in the United States, United Kingdom, and some other countries for measuring vehicle speeds, wind speeds, and in sports.
What is a meter per second?
A meter per second (m/s) is the SI (International System of Units) unit of speed, representing the distance in meters traveled in one second. It’s commonly used in scientific contexts, physics calculations, and for measuring wind speeds in meteorology.
Why would I need to convert miles per hour to meters per second?
This conversion is commonly needed when working with scientific calculations or international standards that require SI units. For example, if you have a speed limit in mph but need to use it in physics equations that require m/s, or if you’re working on an international project where SI units are standard.
How accurate is this converter?
Our converter uses the exact conversion factor of 0.44704 meters per second per mile per hour, which is mathematically precise. The calculator can display results with up to 9 decimal places for high precision needs, though most practical applications don’t require this level of precision.
What are some common speed benchmarks in both mph and m/s?
- Average walking speed: 3.1 mph (1.4 m/s)
- Average running speed: 5-7.5 mph (2.2-3.4 m/s)
- US residential speed limit: 25 mph (11.2 m/s)
- US highway speed limit: 55-70 mph (24.6-31.3 m/s)
- UK motorway speed limit: 70 mph (31.3 m/s)
- Speed of sound in air at sea level: 767 mph (343 m/s)
How do I convert meters per second back to miles per hour?
To convert from meters per second to miles per hour, multiply the meters per second value by 2.23694 (or divide by 0.44704). Alternatively, you can use our Meter per Second to Mile per Hour Converter for quick and accurate conversions.
