Result and Explanation
The conversion of 120 mph to meters per second is approximately 53.6448 m/s.
Since 1 mile equals 1,609.34 meters and 1 hour equals 3,600 seconds, we convert mph to m/s by multiplying by 1,609.34 and dividing by 3,600, giving 120 mph as about 53.6448 meters per second. This helps in understanding speed in metric units for scientific or technical uses.

Conversion Formula
The formula to convert miles per hour (mph) to meters per second (m/s) is: (mph) × 1609.34 / 3600. This works because there are 1,609.34 meters in a mile and 3,600 seconds in an hour. For example, for 120 mph: 120 × 1609.34 / 3600 = 53.6448 m/s. This calculation adjusts for the metric system and time units.
Conversion Example
- Convert 60 mph to m/s:
- Multiply 60 by 1609.34 to get meters per hour: 60 × 1609.34 = 96560.4 meters/hour.
- Divide by 3600 to convert hours to seconds: 96560.4 / 3600 ≈ 26.8218 m/s.
- Convert 45 mph to m/s:
- 45 × 1609.34 = 72420.3 meters/hour.
- Divide by 3600: 72420.3 / 3600 ≈ 20.1173 m/s.
- Convert 90 mph to m/s:
- 90 × 1609.34 = 144840.6 meters/hour.
- Divide by 3600: 144840.6 / 3600 ≈ 40.2335 m/s.
- Convert 150 mph to m/s:
- 150 × 1609.34 = 241401 meters/hour.
- Divide by 3600: 241401 / 3600 ≈ 67.0558 m/s.

Conversion Definitions
mph
mph stands for miles per hour, a unit measuring how many miles an object travels in one hour. It is used mainly in the United States and United Kingdom to describe vehicle speed or travel velocity, combining distance (miles) and time (hours).
ms
ms means meters per second, a metric unit expressing the distance in meters traveled in one second. It is common in scientific contexts to quantify speed, where meters and seconds are standard SI units used for precise measurement and calculations.
Conversion FAQs
How precise is the conversion from 120 mph to meters per second?
The conversion is accurate up to four decimal places based on the established formula. Slight variations may occur due to rounding, but generally, the value 53.6448 m/s reliably represents 120 mph for most practical applications, including scientific calculations or engineering.
Why do we divide by 3600 in the formula?
Dividing by 3600 converts hours into seconds because there are 3,600 seconds in an hour. This step adjusts the speed from miles per hour to meters per second, aligning units with the SI system for consistent measurement in scientific contexts.
Can I use this conversion for other speeds like 200 mph?
Yes, the same formula applies to any mph value. You simply multiply the mph by 1609.34 and then divide by 3600 to get meters per second, regardless of the specific speed being converted.
