28 mph is approximately 12.5064 meters per second (mps).
To convert miles per hour (mph) to meters per second (mps), you multiply by a factor because one mile equals 1609.344 meters, and one hour equals 3600 seconds. So, 28 mph converted to mps gives you the speed in metric units, useful for science and engineering applications.

Conversion Formula
The formula to convert mph to mps is:
mps = mph × 0.44704
This works because 1 mile equals 1609.344 meters and 1 hour equals 3600 seconds, so:
- 1 mph = 1609.344 meters / 3600 seconds
- 1 mph = 0.44704 meters per second
If you take 28 mph, multiply by 0.44704:
28 × 0.44704 = 12.5064 mps
This conversion lets you change speed units from imperial to metric system.
Conversion Example
- Convert 45 mph to mps:
- Multiply 45 by 0.44704
- 45 × 0.44704 = 20.1168 mps
- So, 45 mph is 20.1168 mps
- Convert 10 mph to mps:
- 10 × 0.44704 = 4.4704 mps
- This means 10 mph equals 4.4704 meters per second
- Convert 60 mph to mps:
- 60 × 0.44704 = 26.8224 mps
- 60 mph is 26.8224 meters per second
- Convert 5 mph to mps:
- 5 × 0.44704 = 2.2352 mps
- Therefore, 5 mph equals 2.2352 meters per second
- Convert 100 mph to mps:
- 100 × 0.44704 = 44.704 mps
- 100 mph converts to 44.704 meters per second

Conversion Definitions
mph (miles per hour): A unit of speed expressing the number of miles traveled in one hour. Commonly used in the United States and United Kingdom for measuring vehicle speeds, mph quantifies how many miles are covered per hour of travel time. It’s an imperial measurement unit.
mps (meters per second): A unit of speed that shows how many meters are traveled in one second. It is part of the metric system, standard in scientific and engineering fields. Mps provides a precise rate of motion in metric lengths per time, useful worldwide for velocity measurements.
Conversion FAQs
Can I convert mph to mps without a calculator?
You can estimate mph to mps by multiplying mph value by 0.45 for a rough result. But for accuracy, using 0.44704 as the multiplier is better. Mental math with 0.45 gives close enough speed for everyday use but not precise for technical needs.
Why is the conversion factor 0.44704?
This number comes from converting miles to meters and hours to seconds. One mile is 1609.344 meters, one hour is 3600 seconds. Dividing 1609.344 by 3600 gives 0.44704, which converts mph into meters per second. It’s the exact ratio between imperial and metric time-distance units.
Is converting mph to mps necessary in real life?
When working in science, engineering, or international travel, converting to mps is useful because metric units easier understood globally. For driving or casual use within the US, mph suffice. But for physics calculations or international speed limits, mps helps avoid confusion.
What happens if I convert mps back to mph?
To get mph from mps, divide the mps value by 0.44704. This reverses the conversion, changing metric speed back to imperial. It’s useful if you have speeds measured in meters per second and want to understand them in miles per hour, common in some regions.
Can wind speed be converted from mph to mps the same way?
Yes, wind speeds in mph can be converted to mps using the same multiplier 0.44704. This allows meteorologists to report wind speed in metric units preferred internationally. The conversion applies universally for any speed measured in miles per hour.
