The conversion of 120 mph equals approximately 53.6448 meters per second (m/s).
This is because 1 mile per hour (mph) equals 0.44704 meters per second (m/s). So, multiplying 120 by 0.44704 gives the speed in m/s, which results in about 53.6448 m/s.
Understanding the Conversion from mph to m/s
The conversion from miles per hour to meters per second is based on the relationship that 1 mile is equal to 1609.34 meters, and 1 hour contains 3600 seconds. To convert mph to m/s, you multiply the speed in mph by the factor 0.44704. This factor stems from dividing 1609.34 meters by 3600 seconds, giving the meters per second equivalent for each mph.

Conversion Formula
The formula to convert mph to m/s multiplies the speed in miles per hour by 0.44704, which is the number of meters in a mile divided by the number of seconds in an hour. For example, converting 60 mph:
- 60 mph x 0.44704 = 26.8224 m/s
This works because it scales the speed from miles per hour into meters per second, adjusting for the length of a mile and the time in seconds.
Conversion Example
Suppose you want to convert 80 mph to m/s:
- Step 1: Take 80 mph.
- Step 2: Multiply 80 by 0.44704.
- Step 3: 80 x 0.44704 = 35.7632 m/s.
- This means 80 mph equals approximately 35.7632 meters per second.
Similarly, for 45 mph:
- Step 1: Start with 45 mph.
- Step 2: Multiply 45 by 0.44704.
- Step 3: 45 x 0.44704 = 20.1168 m/s.
- So, 45 mph is about 20.1168 meters per second.
