28 miles per hour (mph) is approximately 12.5072 meters per second (mps).
To convert 28 mph to mps, multiply the speed by the factor that converts miles to meters and hours to seconds. Since 1 mile equals 1609.344 meters and 1 hour equals 3600 seconds, we apply these to get the equivalent speed in meters per second.

Conversion Formula
The formula to convert miles per hour (mph) to meters per second (mps) uses the relationship between miles and meters, and hours and seconds:
mps = mph × (1609.344 meters / 1 mile) ÷ (3600 seconds / 1 hour)
This means you multiply the speed in mph by 1609.344 to convert it to meters per hour, then divide by 3600 to convert hours to seconds.
For example, converting 28 mph:
- Multiply: 28 × 1609.344 = 45061.632 meters per hour
- Divide: 45061.632 ÷ 3600 = 12.5171 meters per second
So, 28 mph equals about 12.5171 mps.
Conversion Example
- Convert 45 mph to mps:
- Multiply 45 × 1609.344 = 72420.48 meters per hour
- Divide 72420.48 ÷ 3600 = 20.1168 mps
- Convert 10 mph to mps:
- Multiply 10 × 1609.344 = 16093.44 meters per hour
- Divide 16093.44 ÷ 3600 = 4.4704 mps
- Convert 5.5 mph to mps:
- Multiply 5.5 × 1609.344 = 8851.392 meters per hour
- Divide 8851.392 ÷ 3600 = 2.4587 mps
- Convert 32 mph to mps:
- Multiply 32 × 1609.344 = 51498.208 meters per hour
- Divide 51498.208 ÷ 3600 = 14.3051 mps

Conversion Definitions
mph (miles per hour): A unit of speed measuring how many miles are covered in one hour. It’s used mainly in the United States and United Kingdom for road and vehicle speeds. One mph equals exactly 1609.344 meters per 3600 seconds.
mps (meters per second): A metric unit of speed describing how many meters traveled in one second. It’s common in scientific contexts and internationally used for expressing speed in the metric system, where 1 mps equals 3.6 kilometers per hour.
Conversion FAQs
Why is the conversion factor 1609.344 divided by 3600?
Because one mile is exactly 1609.344 meters, and one hour has 3600 seconds. To convert miles per hour to meters per second, you multiply by meters per mile, then divide by seconds per hour, to convert distance and time units respectively.
Can I approximate 28 mph to mps without precise decimals?
Yes, you can round 28 mph to about 12.5 mps, which is close for rough estimates. But for engineering or physics, it’s better to use the exact conversion to avoid errors.
Is meters per second faster than miles per hour?
They measure speed differently but neither is faster. Meters per second is metric, miles per hour imperial. One mph equals about 0.447 mps, so speeds numerically lower in mps might actually be faster than mph values.
Why might someone convert mph to mps?
Because meters per second is standard in scientific research, physics, or engineering fields. Also, countries using metric units prefer mps for consistent measurement and calculations involving speed.
How precise is the conversion for everyday use?
The conversion is exact based on defined units, but for everyday driving or casual needs, rounding to two decimal places suffices. More decimals can be used for technical or scientific accuracy.
