📏 How This Converter Works
This is a bidirectional converter that works in real-time:
- Decades → Years: When you type in the decades field, the years field automatically updates
- Years → Decades: When you type in the years field, the decades field automatically updates
- No swapping needed: Both conversions happen simultaneously
- Real-time: Updates happen as you type, no button clicks required
// Bidirectional Conversion Logic:
years = decades × 10
decades = years ÷ 10
// Example 1: Type "3" in decades
years = 3 × 10 = 30
// Example 2: Type "75" in years
decades = 75 ÷ 10 = 7.5
years = decades × 10
decades = years ÷ 10
// Example 1: Type "3" in decades
years = 3 × 10 = 30
// Example 2: Type "75" in years
decades = 75 ÷ 10 = 7.5
