20 meters per second converts to approximately 44.7387 miles per hour (mph).
To convert meters to mph, you need to first understand that meters measure distance while mph measure speed. By knowing how many meters you travel in one second, you can convert that speed into how many miles you travel in an hour.

Conversion Formula
The formula to convert meters per second (m/s) to miles per hour (mph) involves multiplying the meter value by 2.23694. This number comes from the relationship between meters and miles, and seconds and hours:
- 1 mile = 1609.344 meters
- 1 hour = 3600 seconds
So, to convert meters per second to miles per hour:
speed (mph) = speed (m/s) × (3600 seconds / 1 hour) ÷ (1609.344 meters / 1 mile)
Which simplifies to:
speed (mph) = speed (m/s) × 2.23694
Example: For 20 meters per second, it would be:
20 × 2.23694 = 44.7388 mph
Conversion Example
- Convert 10 meters per second to mph:
- Multiply 10 by 2.23694
- 10 × 2.23694 = 22.3694 mph
- Result is 22.3694 mph
- Convert 5 meters per second to mph:
- Multiply 5 by 2.23694
- 5 × 2.23694 = 11.1847 mph
- Result is 11.1847 mph
- Convert 30 meters per second to mph:
- Multiply 30 by 2.23694
- 30 × 2.23694 = 67.1082 mph
- Result is 67.1082 mph
- Convert 2.5 meters per second to mph:
- Multiply 2.5 by 2.23694
- 2.5 × 2.23694 = 5.59235 mph
- Result is 5.59235 mph
- Convert 15 meters per second to mph:
- Multiply 15 by 2.23694
- 15 × 2.23694 = 33.5541 mph
- Result is 33.5541 mph

Conversion Definitions
Meters: A meter is a unit measuring length in the metric system equal to 100 centimeters or approximately 39.37 inches. It is the base unit of length in the International System of Units (SI), commonly used worldwide for distances and heights in science and everyday life.
Miles per hour (mph): Miles per hour is a unit of speed expressing how many miles are traveled in one hour. It is often used in the United States and the United Kingdom to measure vehicle speeds, road limits, and general velocity in terms of miles covered per time.
Conversion FAQs
Can meters be directly converted to mph without knowing time?
No, meters alone measure distance, so without the time factor, you cannot get a speed like mph. MPH measures how far traveled over one hour, so the time component is necessary to convert meters per second or any distance per time to mph.
Why does the conversion factor 2.23694 come into play?
This factor is derived from converting meters to miles and seconds to hours. Since 1 mile equals 1609.344 meters and 1 hour equals 3600 seconds, dividing 3600 by 1609.344 gives the conversion factor 2.23694, which converts meters per second to miles per hour.
What if I want to convert meters per minute to mph?
First, convert meters per minute to meters per second by dividing by 60, then multiply result by 2.23694 to get mph. Direct conversion isn’t possible without adjusting the time units to seconds per hour basis.
Is negative meter value valid in speed conversion?
Negative values can represent direction, such as moving backwards or opposite direction. While speeds are usually positive, negative meters per second can indicate velocity direction, so mph will also be negative, reflecting that direction.
Are there other units for speed similar to mph?
Yes, kilometers per hour (km/h) is widely used globally, especially metric countries. Knots are used in aviation and marine navigation. To convert meters per second to km/h, multiply by 3.6 instead of 2.23694.
