FAQ
Does the result include leap seconds or daylight saving changes?
No. The conversion uses the fixed SI definition of the second. Adjust manually if you are aligning with civil clock transitions or rare leap seconds.
How do I express the answer as weeks and days?
Take the whole number of weeks, then multiply the decimal remainder by 7 to obtain days. Convert the remaining decimal day to hours by multiplying by 24.
Can I enter scientific notation for very large values?
Yes. The input accepts decimals and exponential notation such as 1.2e9 for 1,200,000,000 seconds.
Is this accurate for fiscal or academic weeks?
If your organization defines custom week lengths, update the divisor to reflect the exact number of seconds in that schedule before relying on the result.
