使い方
- Enter a duration using HH:MM:SS.
- Select Convert to seconds.
- Review or copy the total seconds.
HH:MM:SS format
Use a non-negative hour value followed by two-digit minutes and seconds, such as 00:05:30 or 12:00:00. Minutes and seconds must be between 00 and 59.
Exact duration conversion
The result is calculated as hours × 3,600 + minutes × 60 + seconds. Hours may be larger than 23 because this tool converts durations rather than clock times.
Private browser processing
Validation and conversion happen in your browser. The entered duration is not sent to a server.
よくある質問
あわせて知りたいこと
Can hours be more than 23?
Yes. This tool accepts any non-negative whole-hour value, so it also works for multi-day durations.
Can I enter minutes or seconds above 59?
No. Use the next larger unit instead, such as 01:02:00 rather than 00:62:00.
Does this convert a time of day?
It converts a duration. It does not apply a time zone or interpret a clock time.
