⏱️ Time Converter
Convert between hours, minutes, seconds, and days instantly.
Time conversions come up more often than you might think — whether you’re planning a project timeline, calculating workout durations, converting a recipe’s cooking time, or figuring out how many seconds are in a workday. Our Time Converter handles it all: hours, minutes, seconds, and days, with instant results that update as you type.
Here’s a real-world example: your project manager says a task will take 72 hours, but your team tracks progress in days. Enter 72 in the value field, select Hours as “From” and Days as “To” — you’ll see 72 h = 3 days instantly. Or maybe your fitness app says you exercised for 7,500 seconds and you want to know the minutes — same tool, one quick conversion.
The use cases are everywhere. Freelancers and consultants convert hours to days when estimating project duration for quotes. Runners and swimmers convert minutes to seconds to compare lap times and splits. Parents planning road trips convert hours and minutes for travel time estimates. Even students use it for homework — converting hours to minutes or days to hours for math and science problems.
This converter uses the standard relationships: 1 hour = 60 minutes, 1 minute = 60 seconds, and 1 day = 24 hours. The results are accurate to 6 decimal places, ensuring you get the precision you need whether you’re doing quick mental checks or precise scheduling calculations.
Frequently Asked Questions
What time units does this converter support?
This tool converts between seconds, minutes, hours, and days. If you need weeks, months, or years, you can chain conversions — for example, convert 14 days to hours, then manually divide by 24 to get weeks.
How many seconds are in an hour or a day?
There are 3,600 seconds in one hour (60 minutes × 60 seconds) and 86,400 seconds in one day (24 hours × 3,600 seconds). The converter uses these exact values internally, so your results are always precise.
Can I convert fractions of a time unit?
Yes! The converter accepts decimal values. For example, entering 1.5 hours gives you 90 minutes. This is useful for converting "1 hour and 30 minutes" into a single unit without separate calculations.
Is this useful for anything beyond simple time conversions?
Definitely. It's great for project management (converting task estimates between hours and days), fitness tracking (seconds to minutes for interval workouts), travel planning (hours to days for trip duration), cooking (minutes to hours for slow-cooker recipes), and even payroll calculations.
