Time Converters
Convert between seconds, minutes, hours, days, and weeks using exact fixed relationships built from the SI second. This hub covers common civil-time mirror pairs for scheduling, logging, and engineering calculations.
Scope & Verification
This hub groups related converter families so you can move from the category level to exact routes with one clear basis per page.
- Families are split so exact-factor, profile-based, density-based, and estimate-style pages do not collapse into one generic answer.
- Leaf pages keep calculator, common values, FAQ, and reverse routes aligned to the same assumption.
- Methodology and verification pages document how those assumptions are chosen and checked.
Explanation
The second is the SI base unit of time and the normalization anchor for every page in this cluster. 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 results stay stable across calculator output, tables, and mirror pages. This cluster excludes variable calendar units like months and years, which do not have one fixed second-based ratio.
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.
