How to Use the Time Converter
Time conversions come up constantly in project planning, travel, billing, and scheduling. This converter handles all common time units instantly.
Step-by-Step Instructions
- 1 Select the unit you are converting from.
- 2 Enter the value.
- 3 Select the unit you are converting to.
- 4 View the converted value.
Understanding the Inputs
Value
The amount of time you want to convert. Enter 90 to convert 90 minutes to hours (result: 1.5), 7 to convert 7 days to weeks (result: 1), or 3600 to convert 3600 seconds to minutes (result: 60). Fractional values like 2.5 hours are fully supported.
How to find it: Look at the time duration you already have. A flight itinerary says 450 minutes. A project deadline says 14 days. A video is 180 seconds long. Enter the number exactly as stated.
Why it matters: The value is the actual time quantity being converted. Entering an incorrect value changes the result. Precision matters, especially for billing, scheduling, and deadlines.
Type: number · Default: 0
From
The time unit your current value is measured in. If your value is in minutes, select minutes. If it is in weeks, select weeks. Choose from seconds, minutes, hours, days, weeks, months, or years.
How to find it: Check the unit label on your source time value. Pay stubs use hours. Shipping estimates use business days. Subscription terms use months. Software timeouts use seconds or milliseconds.
Why it matters: The From unit establishes the baseline for conversion. Converting from minutes to hours divides by 60, while converting from seconds to hours divides by 3600. An incorrect From unit produces a wildly wrong result.
Type: select · Default:
To
The target time unit you want the result expressed in. To express 90 minutes in hours, select hours as To. To express 14 days in weeks, select weeks. To express 3 years in days, select days as To.
How to find it: This depends on what format you need the answer in. Time tracking software might bill in hours. A project plan needs days. An age calculation needs years.
Why it matters: The To unit determines how the result is displayed. Converting the same value to different units gives different numbers (90 minutes = 1.5 hours = 5400 seconds).
Type: select · Default:
Tips & Best Practices
- ✓ For payroll, remember 40 hours = 1 standard work week.
- ✓ Months and years are approximate. Use days for precise calculations.
- ✓ Use this to compare project timelines across different time units.
