Time Converters
Convert between fixed civil time units used in scheduling, time tracking, and engineering calculations. The SI second is the base reference, and exact ratios (60, 24, and 7) keep all minute, hour, day, and week conversions consistent.
Explanation
The second is the SI base unit of time and is the normalization anchor for every converter family in this hub. One minute equals 60 seconds, one hour equals 3,600 seconds, one day equals 86,400 seconds, and one week equals 604,800 seconds. Every factor is derived directly from these fixed integers, so ratios are stable and reproducible across mirror pages. Time conversions here are purely multiplicative and use no offsets. For clarity, time conversions are grouped by second-based normalization and common civil time relationships.
Time converters are grouped into directional families so each leaf keeps one stable conversion model.

Frequently Asked Questions
How are these time factors derived?
Each factor is derived by expressing both units in seconds and simplifying the ratio. Because the second is the SI base unit of time, all conversions remain internally consistent.
Are these ratios exact?
Yes. Minute, hour, day, and week factors are fixed integer multiples of the second, so the ratios do not drift.
Why are months and years not included here?
Months and years are not fixed-length units, so this hub keeps only fixed time units for exact conversions.
