// Bidirectional Conversion Logic (US Standard):
ml = cups × 236.588
cups = ml ÷ 236.588
// Example 1: Type "2" in cups
ml = 2 × 236.588 = 473.176 ml
// Example 2: Type "500" in ml
cups = 500 ÷ 236.588 = 2.113 cups
ml = cups × 236.588
cups = ml ÷ 236.588
// Example 1: Type "2" in cups
ml = 2 × 236.588 = 473.176 ml
// Example 2: Type "500" in ml
