Time Duration Conversions

Time conversion covers everything from nanoseconds to millennia. Essential for scientific calculations, project planning, and everyday scheduling.

Standard Units

Second is the SI base unit. Minutes (60s), hours (3600s), days (86,400s), weeks (7 days), months, and years form the common hierarchy.

Scientific Time

Milliseconds, microseconds, and nanoseconds for precise measurements. Atomic clocks and physics experiments require extreme precision.

Calendar Systems

Different calendar systems affect year lengths. Leap years, different month lengths, and time zones add complexity to conversions.

Common Applications

Scientific research, project management, scheduling, sports timing, computer systems, and astronomical calculations.

Conversion Tips

1 year ≈ 365.25 days (accounting for leap years). 1 day = exactly 24 hours = 1440 minutes = 86,400 seconds.
