⛽ How This Converter Works

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

MPG → KPL: When you type in the MPG field, the KPL field automatically updates
KPL → MPG: When you type in the KPL field, the MPG field automatically updates
No swapping needed: Both conversions happen simultaneously
Real-time: Updates happen as you type, no button clicks required

// Conversion Factors:
1 mile = 1.609344 kilometers
1 US gallon = 3.785411784 liters

// MPG to KPL Formula:
KPL = MPG × (1.609344 / 3.785411784)
KPL = MPG × 0.425144

// Example: 30 MPG
KPL = 30 × 0.425144 = 12.75432 ≈ 12.75 KPL
