Vzorec
How this is calculated
Hours are converted to every common time unit by multiplying or dividing by the exact fixed ratios between SI time units. One hour equals exactly 60 minutes and exactly 3,600 seconds — no rounding is involved. Milliseconds are 3,600,000 per hour by the same logic. Going in the other direction: 24 hours make one day, and 7 days make one week, so 168 hours make one week exactly.
Longer units — months and years — require an average, because calendar months and years are not uniform. This converter uses the Gregorian calendar average: a year is 365.25 days (accounting for leap years every 4 years, minus century adjustments), giving 8,766 hours per year. A month is 365.25 ÷ 12 = 30.4375 days, or 730.5 hours. These are the same averages used by ISO 8601 and most engineering standards.
Decimal hours (e.g. 1.5 hours = 90 minutes) are fully supported. The fraction-of-a-day bar caps at 24 hours — it shows how much of a single day the entered duration represents.
Často kladené otázky
Multiply by 60: 1.5 × 60 = 90 minutes. In general, minutes = hours × 60 and seconds = hours × 3,600.
Using the Gregorian calendar average of 365.25 days per year: 365.25 × 24 = 8,766 hours per year. Exact calendar years vary by whether a leap year is included.
On average 730.5 hours (365.25 ÷ 12 × 24). Individual months range from 672 hours (28-day February) to 744 hours (31-day months).
