Real-World Examples

Example 1 (Student Homework)

Binary: 101110 → Decimal: 46
(1×32 + 0×16 + 1×8 + 1×4 + 1×2 + 0×1 = 32+8+4+2 = 46)

Example 2 (Web Developer)

Decimal: 255 → Binary: 11111111
(Commonly used in RGB color values and subnet masks)

Example 3 (Embedded Systems)

A sensor sends back 10011001. What is the decimal value? → 153
(Used to interpret raw sensor data in real-time applications)

This is what makes the Binary Decimal Converter so useful: it is accurate, fast, and clear for anybody who works with digital systems.
