The problem is that 5.5 feet is often mistakenly interpreted as 5 feet 5 inches. However, the decimal part represents a fraction of a foot, not inches. Since one foot equals 12 inches, 0.5 feet = 6 inches, so 5.5 feet is actually 5 feet 6 inches. To convert decimal feet correctly, multiply the fractional part by 12 to get the number of inches.
Rounding the inch to 2.5 cm feels harmless, but the exact value is 2.54 cm, a 1.6% error. Over a 100-inch measurement that is already 4 cm off, and the error compounds in chained calculations. Use the exact definition: 1 inch = 2.54 cm, exactly.
