Time Unit Converter
Convert between different time units.
📘 How It Works
Base Unit (Seconds)
Seconds serve as the base unit. All conversions go through seconds: input is first converted to seconds, then to target units.
Fixed Conversion Factors
Standard factors: 60 sec/min, 3600 sec/hour, 86400 sec/day, 604800 sec/week. Consistent for accurate conversions.
Approximated Large Units
Months use 30 days (2,592,000 seconds) and years use 365 days (31,536,000 seconds). Standard approximations for simple calculation.
Simultaneous Calculation
All time representations are computed and displayed together, showing milliseconds through years for complete reference.
Smart Formatting
Results use locale-aware formatting with appropriate decimal places. Both large and small values display readably.
💡 Common Use Cases

Convert video lengths between seconds and hours/minutes. How many hours is a 7200-second podcast?
SLA & Uptime Calculations
Convert uptime percentages to downtime. 99.9% uptime = how many minutes of downtime per year?
