MPH ↔ FPS Converter
Convert between Miles Per Hour and Feet Per Second instantly
📚 MPH ↔ FPS Conversion Details
MPH to FPS Formula
To convert miles per hour to feet per second, multiply MPH by approximately 1.46667.
FPS to MPH Formula
To convert feet per second to miles per hour, divide FPS by approximately 1.46667.
Conversion Factor
The exact conversion factor is:
1 FPS = 0.68181818 MPH
This comes from: 1 mile = 5280 feet, 1 hour = 3600 seconds
Common Uses
- Physics calculations
- Engineering projects
- Sports speed analysis
- Vehicle speed conversion
📏 How This Converter Works
This is a bidirectional converter that works in real-time:
- MPH → FPS: When you type in the MPH field, the FPS field automatically updates
- FPS → MPH: When you type in the FPS field, the MPH field automatically updates
- No swapping needed: Both conversions happen simultaneously
- Real-time: Updates happen as you type, no button clicks required
FPS = MPH × (5280 ÷ 3600)
FPS = MPH × 1.46666667
MPH = FPS ÷ (5280 ÷ 3600)
MPH = FPS ÷ 1.46666667
// Example 1: 60 MPH to FPS
FPS = 60 × 1.46666667 = 88
// Example 2: 100 FPS to MPH
MPH = 100 ÷ 1.46666667 ≈ 68.18

| MPH | FPS | Meters/Sec | Km/H |
|---|---|---|---|
| 10 MPH | 14.67 FPS | 4.47 m/s | 16.09 km/h |
| 30 MPH | 44.00 FPS | 13.41 m/s | 48.28 km/h |
| 45 MPH | 66.00 FPS | 20.12 m/s | 72.42 km/h |
| 60 MPH | 88.00 FPS | 26.82 m/s | 96.56 km/h |
| 70 MPH | 102.67 FPS | 31.29 m/s | 112.65 km/h |
| 88 MPH | 129.07 FPS | 39.34 m/s | 141.62 km/h |
🔢 The Math Behind the Conversion
The conversion between MPH and FPS is based on these fundamental units:
1 hour = 3600 seconds
Therefore:
1 MPH = 1 mile per hour
= (5280 feet) / (3600 seconds)
= 5280 ÷ 3600 feet per second
= 1.46666667 feet per second
This means that 1 mile per hour is exactly equal to 1.46666667 feet per second.
