20 meters per second is approximately 44.7387 mph.
To convert meters to miles per hour, you must convert the distance from meters to miles, and the time from seconds to hours. This ensures the units match for speed in miles per hour.

Conversion Formula
The conversion from meters per second (m/s) to miles per hour (mph) involves multiplying the value by a fixed factor. Since 1 meter equals about 0.000621371 miles, and 1 second is 1/3600 of an hour, you combine these to get the conversion factor.
Formula:
mph = meters/second × (0.000621371 miles / 1 meter) × (3600 seconds / 1 hour)
When simplified:
mph = meters/second × 2.23694
Example: Convert 20 meters per second to mph
- Multiply 20 by 0.000621371 = 0.01242742 miles per second
- Multiply 0.01242742 by 3600 = 44.7387 mph
Conversion Example
- Example 1: Convert 10 m/s to mph
- 10 × 2.23694 = 22.3694 mph
- So, 10 meters per second equals about 22.3694 mph.
- Example 2: Convert 5.5 m/s to mph
- 5.5 × 2.23694 = 12.3032 mph
- 5.5 m/s is approximately 12.3032 mph.
- Example 3: Convert 30 m/s to mph
- 30 × 2.23694 = 67.1082 mph
- 30 meters per second converts to 67.1082 mph.
- Example 4: Convert 0 m/s to mph
- 0 × 2.23694 = 0 mph
- Zero meters per second means zero mph.

Conversion Definitions
Meters: A meter is a unit of length in the metric system, equal to 100 centimeters or about 39.37 inches. It measures distance or length, used worldwide in science, engineering, and everyday measuring tasks. It forms part of the International System of Units (SI).
Mph: Miles per hour (mph) is a unit of speed commonly used in the United States and United Kingdom. It represents how many miles are traveled in one hour. It is often used in transportation, vehicle speed limits, and various speed measurements.
Conversion FAQs
Why multiply meters per second by 2.23694 to get mph?
The factor 2.23694 comes from converting meters to miles, and seconds to hours. Since 1 meter equals 0.000621371 miles, and 1 hour equals 3600 seconds, multiplying meters/second by (0.000621371 × 3600) yields miles per hour. This combined factor simplifies the conversion.
Can negative meters per second values be converted to mph?
Yes, negative meters per second values convert directly to negative mph values. Negative speed typically refers to direction opposite to a chosen reference. The math works same, just the sign indicates direction rather than magnitude.
Is the conversion factor exact or approximate?
The factor 2.23694 is a rounded approximation based on precise constants. The exact value is slightly more detailed, but for practical purposes, 2.23694 provides enough accuracy for most calculations involving speed conversions.
How to convert mph back to meters per second?
To convert mph back to meters per second, divide the mph value by 2.23694. This reverses the multiplication used in forward conversion, converting miles per hour to meters per second.
Does this conversion apply to any speed measured in meters?
This conversion applies specifically to speed in meters per second. If meters are used as length only, without time, conversion to mph is meaningless. Always ensure the speed has units of meters per second before converting.
