Conversion reference

• 1 second = 1 000 milliseconds
• 1 minute = 60 seconds = 60 000 ms
• 1 hour = 60 minutes = 3 600 seconds = 3 600 000 ms
• 1 day = 24 hours = 86 400 seconds = 86 400 000 ms
• 1 week = 7 days = 168 hours = 604 800 seconds

Common durations

• API timeout: 30 000 ms = 30 seconds
• JWT expiry (1 hour): 3 600 seconds = 3 600 000 ms
• Cache TTL (1 day): 86 400 seconds
• Session expiry (2 weeks): 1 209 600 seconds
• Unix timestamp difference: seconds since 1970-01-01 UTC

Use cases

• Setting server timeouts and cache expiry values
• Converting animation durations (CSS uses seconds, JS uses milliseconds)
• Understanding database timestamp differences
• Calculating SLA and uptime windows
