* mph measures speed, not acceleration: Miles per hour (mph) is a unit of speed, which tells you how fast something is moving. Acceleration, on the other hand, measures how quickly something's speed changes.
* Acceleration has units of speed per time: The standard unit for acceleration is meters per second squared (m/s²). This means it tells you how many meters per second the speed changes every second.
How to convert acceleration due to gravity:
While you can't directly express acceleration in mph, you can convert the standard unit (m/s²) into mph/s (miles per hour per second).
Here's the conversion:
1. Standard acceleration due to gravity: 9.8 m/s²
2. Conversion factor: 1 meter = 0.000621371 miles and 1 second = 1/3600 hours
3. Calculation: 9.8 m/s² * (0.000621371 miles/meter) * (3600 s/hour)² = 22.03 mph/s
Important Note: While 22.03 mph/s is a valid conversion, it's not a commonly used unit for acceleration due to gravity. It's generally more practical and meaningful to use the standard unit of m/s².
