Work out time converter instantly with clear inputs, formula shown and shareable results.
Each time unit is defined as a multiple of the second, so the conversion runs in two steps: multiply by the source unit's factor to reach second, then divide by the target unit's factor. One factor per unit covers every pair in the list. Months and years have no fixed length, so the 30-day month and 365.25-day Julian year are used here as conventions.
Two-step conversion
result = value × factor(from) ÷ factor(to)
Base value
base (second) = value × factor(from)
With 10 units, direct pairs would mean 90 factors to maintain. Going via second needs one factor per unit and gives the same answer.
Yes. The first is the unit your figure is already in; the second is what you want it in. Swapping them inverts the result.
