📏 How This Converter Works
This is a bidirectional converter that works in real-time:
- Celsius → Rankine: When you type in the Celsius field, the Rankine field automatically updates
- Rankine → Celsius: When you type in the Rankine field, the Celsius field automatically updates
- No swapping needed: Both conversions happen simultaneously
- Real-time: Updates happen as you type, no button clicks required
Rankine = (Celsius × 9/5) + 491.67
Celsius = (Rankine - 491.67) × 5/9
// Example 1: Type "100" in Celsius
Rankine = (100 × 9/5) + 491.67 = 671.67
// Example 2: Type "671.67" in Rankine
Celsius = (671.67 - 491.67) × 5/9 = 100
