How to convert minutes to decimal hours

Converting time to decimal hours makes it easier to calculate pay. Use the formula: hours + (minutes ÷ 60) + (seconds ÷ 3600).

  • 30 minutes = 0.5 hours (30 ÷ 60)
  • 15 minutes = 0.25 hours (15 ÷ 60)
  • 6 minutes ≈ 0.1 hours (6 ÷ 60)

Common rounding rules

Companies often round to keep time entry consistent. Popular methods include: 0.1h decimals, nearest minute, and 5, 6, 7.5, 10, 15, or 30-minute increments.

  • 6-minute rounding: 1/10 of an hour (0.1h)
  • 7.5-minute rounding: 1/8 of an hour (0.125h)
  • 15-minute rounding: quarter-hour (0.25h)

  • Use the hours to minutes conversion formula: minutes = hours × 60. Example: 2 hours × 60 = 120 minutes.

  • Formula: minutes = hours × 60. For hour:minute (HH:MM), total minutes = (HH × 60) + MM.

  • 1.5 hours × 60 = 90 minutes.

  • (2 × 60) + 30 = 120 + 30 = 150 minutes.

  • Multiply hours (hr) by 60. Example: 0.75 hr × 60 = 45 min.

  • No. 'hr' (singular) and 'hrs' (plural) both convert using the same rule: minutes = hours × 60.

  • Sum all hours, convert fractional hours to minutes (hours × 60), add minutes, then apply any rounding rules required by payroll.

  • Split hours and minutes. Total minutes = (hours × 60) + minutes. Example: 7:45 → (7 × 60) + 45 = 465 minutes.

  • An hours minutes converter changes hours to minutes and back. Enter hours (or HH:MM) and it returns total minutes instantly.

  • If hours are in A2, minutes = A2*60. If time is HH:MM in A2 (as time), use =HOUR(A2)*60 + MINUTE(A2).

  • Replace h with ×60. Example: (3.2 h) → 3.2 × 60 = 192 min.

  • Total minutes = (hours × 60) + minutes + (seconds ÷ 60). Example: 1:10:30 → 60 + 10 + 0.5 = 70.5 minutes.

  • Hour‑minute conversion translates between time units using 1 hour = 60 minutes so calculations are consistent.

  • First convert to minutes (hours × 60), then to decimal hours by dividing by 60 if needed. Example: 1:30 → 90 min → 1.5 h.

  • Yes. Divide minutes by 60 to get hours. Example: 135 minutes ÷ 60 = 2.25 hours (2 hours 15 minutes).

  • 0.1 hours × 60 = 6 minutes. Common in 6‑minute rounding for timesheets.

  • 7.5 × 60 = 450 minutes.

  • Convert to minutes, then round to your rule (nearest 1, 5, 6, 7.5, 10, 15, or 30 minutes) before converting back if needed.
