Common time unit conversions: seconds to minutes (s to min), minutes to hours (min to h), hours to days (h to d), days to weeks (d to week), milliseconds to seconds (ms to s), microseconds to milliseconds (μs to ms), nanoseconds to microseconds (ns to μs). Convert time units easily with precise calculations.

Principles & formula sources

Time conversion is a fixed ratio problem. The SI base unit is the second (s); minute/hour/day/week are exact multiples for duration work.

This converter treats day = 24 h and week = 7 days as fixed durations; it does not model time zones, leap seconds, or variable months/years.

Formula & example

Formula: value_target = value_source * (source_to_s) / (target_to_s).

Example: 90 min = 1.5 h; 2 d = 172800 s.

Common errors & notes

  • Month/year are variable calendar units—use seconds for strict durations.
  • Prefixes ms/μs/ns are easy to misread; verify the symbol.
  • Large durations may be clearer in scientific notation.

Practical use cases

Time conversions help align experiment logs, device sampling intervals, and production schedules that mix seconds, minutes, and hours.

When comparing datasets, convert all times to a single base unit before calculating rates.
