The conversion of 18 meters per second (mps) to miles per hour (mph) equals approximately 40.23 mph.
To convert from meters per second to miles per hour, you multiply the speed in mps by 2.23694, because 1 meter per second equals about 2.23694 miles per hour. This conversion is based on the fact that 1 mile is 1609.34 meters, and 1 hour has 3600 seconds.
Conversion Result
18 meters per second is roughly 40.23 miles per hour, a speed comparable to a fast highway driving pace.

Conversion Formula
The formula to convert meters per second to miles per hour is: mph = mps × 2.23694. This works because there are 1609.34 meters in a mile, and 3600 seconds in an hour. So, dividing 3600 by 1609.34 gives approximately 2.23694, which is used as the conversion factor.
For example, if you have 10 mps: 10 × 2.23694 = 22.3694 mph. It scales the speed from metric to imperial units based on distance and time conversion factors.
Conversion Example
- Convert 25 mps:
- Multiply 25 by 2.23694.
- 25 × 2.23694 = 55.9235 mph.
- This means 25 meters per second equals about 55.92 miles per hour.
- Convert 5 mps:
- Multiply 5 by 2.23694.
- 5 × 2.23694 = 11.1847 mph.
- So, 5 meters per second is approximately 11.18 miles per hour.
- Convert 30 mps:
- Multiply 30 by 2.23694.
- 30 × 2.23694 = 67.1082 mph.
- Thus, 30 meters per second roughly equals 67.11 miles per hour.

Conversion Definitions
mps: Meters per second (mps) measures the speed or velocity indicating how many meters an object travels in one second, commonly used in physics and engineering to describe movement or flow rates.
mph: Miles per hour (mph) is a unit of speed expressing how many miles an object travels in one hour, standard in the United States and UK for road speeds and transportation velocities.
Conversion FAQs
Why is the conversion factor 2.23694 used for mps to mph?
This factor comes from dividing 3600 seconds in an hour by 1609.34 meters in a mile, which results in approximately 2.23694. It ensures distances in meters per second are accurately scaled to miles per hour, maintaining measurement integrity.
Can I convert any mps value to mph with the same formula?
Yes, the formula mph = mps × 2.23694 applies universally for converting meters per second to miles per hour, regardless of the specific speed value. Just multiply your mps number by this factor for the mph equivalent.
Is there a way to estimate mph from mps without a calculator for quick approximation?
For rough estimates, remember that 1 mps is about 2.24 mph. So, multiplying your mps value by 2.2 or 2.3 gives a close approximation without precise calculation, handy in situations needing quick mental conversions.
