Panduan Pengguna Lengkap
Apakah itu Kalkulator Masa?
A time calculator helps you find the difference between two times, add or subtract a duration from a time, convert between units (seconds, minutes, hours, days, weeks), and compute the duration between start and end times—including across midnight.
Difference = |Time 2 − Time 1| | Duration = End − Start (or across midnight)
Use it for work hours, travel time, project duration, or any task that requires time arithmetic or unit conversion.
Format Masa
HH:MM atau HH:MM:SS in 24-hour format. Examples: 09:00, 14:30, 23:59:59.
Hours 0–23, minutes and seconds 0–59.
Jenis Pengiraan
Perbezaan Masa
Absolute difference between two clock times. Always a positive duration.
Tambah/Tolak Masa
Add or subtract hours, minutes, or seconds from a time. Result wraps within 24 hours.
Tukar Unit Masa
Convert a numeric amount from one unit to another (e.g. 2 hours to minutes, days to seconds).
Kira Tempoh
Duration from start to end time. If end is earlier than start, the next day is assumed (e.g. 23:00 to 02:00 = 3 hours).
Cara Menggunakan Kalkulator Ini
- Select the mode: Time Difference, Add/Subtract, Convert Units, or Duration
- Enter your times or values in the shown fields (use 24-hour format for clock times)
- Click 'Calculate' to see the result
- Review the main result, detail cards (hours, minutes, seconds, total seconds), and step-by-step solution
- Use the chart to compare values visually
- Click 'Reset' to restore defaults and clear results
Memahami Keputusan Anda
Main result
The primary answer: time difference or duration in HH:MM:SS, or the converted value with unit. Shown in the highlighted card at the top.
Detail cards
Hours, minutes, seconds, and total seconds break down the result. For unit conversion, the cards show input value, from-unit, result, and to-unit.
Step-by-step
Shows how the calculation was performed: converting to seconds, applying the operation, and converting back to hours, minutes, and seconds where applicable.
Understanding the Chart
The bar chart compares the relevant values in seconds: for difference or duration you see the two times and the result; for add/subtract you see start time, amount added or subtracted, and result; for conversion you see the from-value and to-value in a common unit.
Time Conversion Reference
Use this table to convert between common time units (values in seconds).
| Unit | Equals (seconds) |
|---|---|
| 1 second | 1 |
| 1 minute | 60 |
| 1 hour | 3,600 |
| 1 day | 86,400 |
| 1 week | 604,800 |
Nota Penting
- Use 24-hour format (0–23). Time difference is always positive.
- Duration can cross midnight (e.g. 23:00 to 02:00 = 3 hours).
- All calculations use seconds internally; the chart shows values in seconds.
