Converting 120 mph to meters per second results in approximately 53.6444 ms.
This is calculated by knowing that 1 mile equals 1609.34 meters, and 1 hour equals 3600 seconds. So, to convert mph to m/s, multiply by 1609.34 and divide by 3600. The calculation for 120 mph is: (120 × 1609.34) / 3600 ≈ 53.6444 m/s.
Conversion Result and Explanation
120 miles per hour equals about 53.6444 meters per second. The conversion involves changing miles to meters and hours to seconds, which manages to express the speed in SI units, making it easier for scientific and technical uses where metric system standards are used.

Conversion Formula
The formula to convert miles per hour (mph) to meters per second (ms) is:
meters per second = (miles per hour × 1609.34) / 3600. This formula works because it converts miles to meters by multiplying with 1609.34, and hours to seconds by dividing by 3600, the number of seconds in an hour, resulting in the speed in m/s.
For example, converting 50 mph involves:
- 50 × 1609.34 = 80467 meters
- 80467 / 3600 ≈ 22.3464 meters per second
Conversion Example
Let’s convert 75 mph to m/s:
- Multiply 75 by 1609.34: 75 × 1609.34 = 120700.5 meters
- Divide by 3600: 120700.5 / 3600 ≈ 33.5274 m/s
- The speed is approximately 33.5274 meters per second.
This shows how to step-by-step change mph to m/s, considering unit conversions.

Conversion Definitions
mph
MPH stands for miles per hour, a unit measuring how many miles an object travels in one hour. It is commonly used in the US and UK for speed limits, vehicle speeds, and racing, representing a speed relative to miles and hours.
ms
MS means meters per second, the SI unit for speed, indicating how many meters an object covers in one second, widely used in physics and engineering to describe velocities and motion.
Conversion FAQs
How accurate is the conversion from mph to m/s?
The conversion from mph to m/s is highly accurate when using the precise value of 1 mile as 1609.34 meters and 1 hour as 3600 seconds. The main source of error comes from rounding results, which can be minimized by using more decimal places.
Why is it useful to convert mph to m/s?
Converting mph to m/s allows for compatibility with SI units, essential in scientific calculations, physics problems, and engineering projects where standardization of units ensures consistency and accuracy across measurements and data analysis.
Can I convert any speed from mph to m/s with the same formula?
Yes, the same formula applies for any speed in mph: multiply by 1609.34 and divide by 3600. It works universally because it is based on fixed unit conversions, making it suitable for all speeds expressed in miles per hour.
