Hours Calculator

Calculate total hours worked between start and end times, convert hours to minutes, add multiple shifts, subtract breaks, and calculate pay based on Australian wage rates.

Quick Answer

To convert hours to minutes, multiply by 60 (e.g. 2 hours = 120 minutes). To calculate total hours worked, enter your shift start and end times below — the calculator handles overnight shifts and deducts breaks automatically.

Hours to Minutes Conversion

Converting hours to minutes is simple multiplication — every hour is 60 minutes — but it's a question people look up constantly, especially when working out cooking times, workout durations, or how long until an event.

Minutes = Hours × 60
Hours = Minutes ÷ 60

2 hours120 minutes
3 hours180 minutes
4 hours240 minutes
7 hours420 minutes
8 hours480 minutes

Worked Example

Question: How many minutes are in 8 hours?
8 × 60 = 480.
Result: 480 minutes.
Did you know? Going the other way — minutes to hours — often trips people up because the remainder isn't in decimal form automatically. 90 minutes is 1.5 hours, but you get there by dividing (90 ÷ 60 = 1.5), not by treating the "30" as a decimal ".30".

Australian Wage Reference

The Australian National Minimum Wage is $24.10 per hour from 1 July 2025, applying to all national system employees covered by an award or agreement.

Penalty Rates

Under most Modern Awards, Monday–Friday work is paid at ordinary time (×1.0). Saturday work is typically ×1.25 or ×1.5. Sunday is ×1.5 or ×2.0. Public holidays attract ×2.0 to ×2.5. Rates vary by award — always check your specific Modern Award on the Fair Work website.

Hours Calculator Cheat Sheet

Hours → minutes: multiply by 60 (3h = 180min)
Minutes → hours: divide by 60 (90min = 1.5h)
Overnight shift: if end time < start time, add 24h before subtracting
Gross pay = Total hours × hourly rate × pay multiplier

Practice Questions

Beginner:

  1. How many minutes are in 3 hours?
    Show answer

    180 minutes (3 × 60).

  2. How many hours are in 90 minutes?
    Show answer

    1.5 hours (90 ÷ 60).

Advanced:

  1. A shift runs from 10:00 PM to 6:00 AM with a 30-minute break. How many hours were worked?
    Show answer

    10 PM to 6 AM is 8 hours (overnight, add 24h to end time before subtracting: 6:00 + 24:00 − 22:00 = 8:00). Minus 30-minute break = 7.5 hours worked.

  2. At $24.10/hour with a time-and-a-half penalty rate, what is the pay for a 6-hour Saturday shift?
    Show answer

    $24.10 × 1.5 × 6 = $216.90.

Frequently Asked Questions

How many minutes are in a certain number of hours?

Multiply the number of hours by 60. For example, 2 hours = 120 minutes, 8 hours = 480 minutes, and 24 hours (a full day) = 1,440 minutes.

How do you calculate total work hours?

For each shift, subtract the start time from the end time. Add all shifts together. For overnight shifts: if end time is before start time, add 24 hours to the end time before subtracting. The calculator above handles all these cases including midnight crossings.

What are Australian overtime rules?

Standard full-time hours in Australia are 38 per week (National Employment Standards). Overtime is typically paid at time-and-a-half for the first 2-3 hours and double time thereafter, depending on your Modern Award or Enterprise Agreement. Casual workers receive a 25% loading instead of leave entitlements. Contact the Fair Work Ombudsman or check your applicable award at fairwork.gov.au.
