120 mph equals approximately 53.6448 meters per second (m/s). This conversion helps understand how fast 120 miles per hour translates into meters per second, a unit often used in scientific measurements or physics calculations.
To convert 120 mph to m/s, you need to know that 1 mile is 1609.34 meters, and 1 hour is 3600 seconds. Since miles per hour (mph) measures speed in miles traveled per hour, converting it to meters per second involves multiplying by the number of meters in a mile and dividing by the number of seconds in an hour. Specifically, the calculation is: 120 mph * 1609.34 meters/mile / 3600 seconds/hour, resulting in approximately 53.6448 m/s.

Conversion Formula
The conversion from miles per hour (mph) to meters per second (m/s) is based on the fact that 1 mile equals 1609.34 meters, and 1 hour equals 3600 seconds. The formula multiplies the speed in mph by 1609.34 and then divides by 3600. to get meters per second. For example, for 120 mph: 120 * 1609.34 / 3600 = 53.6448 m/s.
Conversion Example
- Convert 60 mph to m/s:
- Multiply 60 by 1609.34: 60 * 1609.34 = 96560.4 meters
- Divide by 3600: 96560.4 / 3600 ≈ 26.82 m/s
- Convert 45 mph to m/s:
- 45 * 1609.34 = 72420.3 meters
- 72420.3 / 3600 ≈ 20.12 m/s
- Convert 90 mph to m/s:
- 90 * 1609.34 = 144840.6 meters
- 144840.6 / 3600 ≈ 40.23 m/s
- Convert 150 mph to m/s:
- 150 * 1609.34 = 241401 meters
- 241401 / 3600 ≈ 67.06 m/s

Conversion Definitions
mph
Miles per hour (mph) is a unit measuring speed, showing how many miles are traveled in one hour. It’s used mainly in the United States and UK to indicate vehicular or travel speeds, combining distance in miles with time in hours.
ms
Meters per second (m/s) is a metric unit of speed, indicating how many meters are covered every second. It’s used in scientific and engineering contexts for precise velocity measurements, especially in physics and motion studies.
Conversion FAQs
How accurate is the conversion from 120 mph to m/s?
The conversion is precise as it relies on the fixed values of 1 mile equals 1609.34 meters and 1 hour equals 3600 seconds. Small rounding differences in the decimal places can slightly affect the final number but generally remain very close to the true value.
Can I convert any mph value to m/s using this method?
Yes, the same formula applies to any mph value. Multiply the mph value by 1609.34 and divide by 3600 to get meters per second. It’s a universal conversion method for any speed expressed in miles per hour.
Why is mph still used instead of m/s in some countries?
mph is a legacy measurement system in countries like the United States and the UK, where it remains common for road signs and vehicle speeds. The metric system, including m/s, is more widespread worldwide but not always used for everyday driving speeds.
