Bidirectional Conversion

This converter works both ways simultaneously:

  • Type in ft/s → mph updates automatically
  • Type in mph → ft/s updates automatically
  • No buttons to click - works as you type

Common Uses

  • Physics calculations
  • Vehicle speed analysis
  • Sports performance metrics
  • Engineering projects

📏 How This Converter Works

This is a bidirectional converter that works in real-time:

  1. FPS → MPH: When you type in the ft/s field, the mph field automatically updates
  2. MPH → FPS: When you type in the mph field, the ft/s field automatically updates
  3. No swapping needed: Both conversions happen simultaneously
  4. Real-time: Updates happen as you type, no button clicks required
// Bidirectional Conversion Logic:
mph = fps × 0.681818
fps = mph × 1.46667

// Example 1: Type "10" in ft/s
mph = 10 × 0.681818 = 6.81818

// Example 2: Type "60" in mph
fps = 60 × 1.46667 = 88
