Time converter
Convert seconds, minutes, hours, days, weeks, months, and years.
What this calculator covers
Use this converter when you need a duration translated across common time units without rebuilding the factor path manually.
Month and year options are approximation-based rather than calendar-aware, so they are best treated as duration conversions rather than date math.
Frequently asked questions
- Why do the month and year results differ from what a calendar shows?
- This converter treats one month as exactly 30 days and one year as exactly 365 days. That makes it reliable for duration arithmetic but not for counting calendar months between two specific dates.
- What is the base unit used for all conversions?
- All conversions go through seconds. The entered value is first converted to seconds, then divided by the target unit's seconds-per-unit factor to produce the output.
- Can I convert a negative duration?
- No. The calculator requires a non-negative value because time durations are treated as non-negative quantities. If you need to work with differences that could be negative, calculate the absolute span first.
- How accurate are the day and week conversions?
- Days and weeks use exact second definitions — 86,400 seconds per day and 604,800 seconds per week — so those results are exact within floating-point precision.

Primary result
36 h
1.5 days converts to 36 h using seconds as the shared base unit.
- Input
- 1.5 days (Days)
- seconds value
- 129,600 s
- Converted value
- 36 h (Hours)
- Exact factor
- 24 h per day
Step-by-step solution
- 1.Start with 1.5 days in Days.
- 2.Normalize it to seconds: 1.5 x 86,400 = 129,600 s.
- 3.Convert the seconds value into Hours: 129,600 / 3,600 = 36 h.
Walkthrough
Visual walkthrough
time conversions normalize the source value into one shared base unit before expressing that same quantity in the target unit.
01
Read the source time
The calculator starts from 1.5 days in Days.
1.5 days
02
Normalize to seconds
1.5 x 86,400 = 129,600 s
Using seconds as the common base keeps every supported time on one exact path.
03
Express the result in Hours
129,600 / 3,600 = 36 h
Re-expressing the base-unit value yields the requested Hours result.
36 h
