Basic Knowledge

Converting Minutes to Hours

To convert minutes to hours, divide by 60. For example, 90 minutes equals 90 ÷ 60 = 1.5 hours, and 150 minutes equals 2.5 hours. Conversely, to convert hours to minutes, multiply by 60.

Decimal Hours and "Hours + Minutes" Notation

1.5 hours means 1 hour 30 minutes. You can convert the decimal portion back to minutes by multiplying by 60 (0.5 × 60 = 30 minutes). In time tracking and payroll calculations, it's customary to express times like 1 hour 45 minutes as 1.75 hours using decimal notation.
