How 6 weeks converts to months
Every time conversion goes through the second, which is the SI base unit for time. 6 weeks is 3,628,800 seconds, and dividing that by the length of one month gives the answer.
1 month = 4.348 weeks 6 ÷ 4.348 = 1.38
Written as a clock reading rather than a decimal, that is 42 days. The decimal form is what a form field or a spreadsheet wants; the clock form is what a schedule wants, and the two are not interchangeable.
Where 6 weeks shows up
Six weeks is 42 days, which the Gregorian average puts at 1.38 months, closer to a month and a half than to the month and a week people sometimes assume. The awkwardness is structural rather than a rounding artefact: a month averages 4.348 weeks, so no whole number of weeks ever equals a whole number of months. If your six weeks starts on a particular date and you need the date it ends, count the calendar at /date/date-difference-calculator instead of multiplying an average.

Frequently asked questions
How many months is 6 weeks?
6 weeks = 1.38 months. 1 month = 4.348 weeks, so the conversion is 6 ÷ 4.348 = 1.38. Because the calculation involves a month or a year, it uses the Gregorian average rather than a real calendar span, so treat it as an estimate.
How long is 6 weeks on a clock?
42 days. That is the same span written out in whole units instead of a decimal, which is usually what you want when you are setting a timer or reading a schedule rather than filling in a form.
Why is this an estimate rather than an exact answer?
Months are 28 to 31 days and years are 365 or 366, so neither has a single fixed length. This page uses the Gregorian average — 365.2425 days a year, which is a twelfth of that, or 30.436875 days, a month. For a span between two real calendar dates, use the date difference calculator instead; it counts the actual days.
