7 mph is approximately 3.1307 meters per second (mps).
To convert miles per hour (mph) to meters per second (mps), we use the fact that 1 mile equals 1609.344 meters, and one hour equals 3600 seconds. So, by multiplying 7 mph by the meters in a mile and dividing by seconds in an hour, we get the result in mps.

Conversion Formula
The formula to convert mph to mps is:
meters per second (mps) = miles per hour (mph) × 1609.344 ÷ 3600
This works because 1 mile equals 1609.344 meters and 1 hour equals 3600 seconds. So, multiplying the mph value by the meters in a mile converts miles to meters, and dividing by seconds in an hour converts hours to seconds, giving the speed in meters per second.
Example calculation for 7 mph:
- Multiply: 7 × 1609.344 = 11265.408 meters per hour
- Divide: 11265.408 ÷ 3600 ≈ 3.1293 meters per second
Conversion Example
- Convert 15 mph to mps:
- Multiply 15 by 1609.344 → 24140.16 meters per hour
- Divide 24140.16 by 3600 → 6.7056 mps
- Convert 3.5 mph to mps:
- 3.5 × 1609.344 = 5632.7 meters per hour
- 5632.7 ÷ 3600 ≈ 1.5646 mps
- Convert 0 mph to mps:
- 0 × 1609.344 = 0 meters per hour
- 0 ÷ 3600 = 0 mps
- Convert 25 mph to mps:
- 25 × 1609.344 = 40233.6 meters per hour
- 40233.6 ÷ 3600 ≈ 11.176 mps
- Convert 50 mph to mps:
- 50 × 1609.344 = 80467.2 meters per hour
- 80467.2 ÷ 3600 ≈ 22.352 mps

Conversion Definitions
mph: Miles per hour (mph) is a unit of speed measuring how many miles an object travels in one hour. It is widely used in the United States and the United Kingdom for vehicle speed limits and other speed-related measurements. One mph equals 1.609344 kilometers per hour.
mps: Meters per second (mps) is a metric unit of speed indicating how many meters something moves in one second. It is commonly used in scientific and engineering contexts because the metric system is based on meters and seconds, making calculations easier and consistent worldwide.
Conversion FAQs
Can I convert mph to mps without a calculator?
You can estimate by remembering that 1 mph is about 0.447 meters per second. So multiply mph by roughly 0.447 to get an approximate mps value. For precise results, use the exact formula with 1609.344 and 3600.
Why is the conversion factor 1609.344 divided by 3600?
Because 1609.344 meters equals 1 mile, and 3600 seconds equals 1 hour. To convert miles per hour into meters per second, miles are converted to meters by multiplying by 1609.344, then hours become seconds by dividing by 3600, resulting in meters per second.
What happens if I use negative mph values in the conversion?
A negative mph indicates movement in the opposite direction. The conversion formula still applies, returning a negative mps value, which represents velocity direction, not just speed magnitude.
Does the speed conversion affect acceleration calculations?
Speed conversion itself doesn’t affect acceleration calculations, but using consistent units is crucial. If speed is in mps, acceleration should be meters per second squared to keep units aligned and calculations correct.
Is meters per second always better than mph for scientific work?
Generally, yes, because meters per second fits into the metric system where distances and times are based on meters and seconds. This consistency makes equations simpler and reduces conversion errors in scientific calculations.
