Conversion Formula
The formula for converting meters per second (mps) to miles per hour (mph) is:
mph = mps × 2.23694
This works because 1 meter equals approximately 0.000621371 miles, and 1 second is 1/3600 of an hour. So when converting speed from mps to mph, you multiply by 3600 seconds/hour and then multiply by the miles per meter factor:
- 1 mps = 1 meter/second
- Convert meters to miles: 1 meter ≈ 0.000621371 miles
- Convert seconds to hours: 1 second = 1/3600 hours
- Thus, 1 mps = 0.000621371 miles / (1/3600 hours) = 0.000621371 × 3600 = 2.23694 mph
Example: To convert 12.5 mps to mph:
12.5 × 2.23694 = 27.96175 mph (rounded to 27.9619)
Conversion Example
- Convert 8 mps to mph:
- Multiply 8 by 2.23694
- 8 × 2.23694 = 17.89552 mph
- So, 8 mps equals approximately 17.8955 mph
- Convert 20 mps to mph:
- 20 × 2.23694 = 44.7388 mph
- This means 20 mps is about 44.7388 mph
- Convert 5.3 mps to mph:
- 5.3 × 2.23694 = 11.8567 mph
- 5.3 mps is close to 11.8567 mph
- Convert 0 mps to mph:
- 0 × 2.23694 = 0 mph
- Speed zero in mps is zero in mph
- Convert 15.8 mps to mph:
- 15.8 × 2.23694 = 35.3155 mph
- 15.8 mps equals about 35.3155 mph

Conversion Definitions
mps (meters per second): Mps stands for meters per second, a unit measuring speed in the metric system. It indicates how many meters an object moves each second. Commonly used in physics, sports, and engineering, it gives a precise velocity measurement based on distance over time.
mph (miles per hour): Mph measures speed in the imperial system, showing how many miles are covered in one hour. It is frequently used in countries like the United States and the UK for transportation and road speed limits, representing distance traveled per time unit.
Conversion FAQs
Why is the conversion factor 2.23694 when converting mps to mph?
The factor 2.23694 comes from converting meters to miles and seconds to hours combined. Since 1 meter is about 0.000621371 miles, and 1 second is 1/3600 of an hour, multiplying these gives 2.23694 mph per mps. It combines both distance and time conversions in one number.
Can I convert negative mps values to mph?
Yes, negative values represent direction or reverse movement. When you convert negative meters per second to mph, the sign stays negative, showing speed in the opposite direction. The magnitude converts using the same factor as positive values.
Is converting mps to mph accurate for all practical uses?
The conversion is mathematically exact based on fixed unit relationships. However, slight rounding differences occur when using decimal approximations. For everyday uses like measuring speed in sports or vehicles, the conversion is sufficiently accurate.
Why does the input field in the conversion tool accept decimals?
Because speed can be fractional, the tool allows decimal inputs to provide precise conversions. Users can enter values like 12.5 or 7.8 mps, and the tool will return the corresponding mph with decimal accuracy.
How can I convert mph back to mps?
To convert mph to mps, divide the mph value by 2.23694. This reverses the calculation, converting miles per hour back to meters per second by adjusting for the difference in distance and time units.
