Days to Weeks Converter (d to wk)
weeks = days ÷ 7.
Divide days by 7. 14 days is 2 weeks. 30 days is about 4.286 weeks — a “30-day month” is not 4 weeks. ISO weeks are a numbering system; the length is still 7 days.

- Due Date from LMPNaegele: EDD = first day of last period + 280 days (40 weeks). Cycles that are not 28 days shift this. Dating scans override the calendar. This is a planning date, not a booking.
- Weeks to DaysMultiply weeks by 7. Pregnancy “weeks” and sprint “weeks” both use this, then life adds exceptions. Two weeks is 14 days. A six-week notice is 42 days, not “a month and a bit” unless you like ambiguity.
- Centuries to YearsA century is 100 years. Multiply. History essays already know this; the page exists because search boxes do not. Two centuries is 200 years. We use the same Julian year as the years-to-days tool if you chain them.
- Days to Calendar YearsDivide by 365, ignoring leap days. Useful for “how many 365-day years is 1,000 days?” It is not a date calculator and will not land on a birthday. For leap years as 366-day blocks, use the sibling page.
- Days to HoursMultiply days by 24. A “two-day” shipping promise is 48 hours if they meant calendar days, and something shadier if they meant business days. This page does not skip Sundays.
- Days to Leap YearsA leap year calendar length is 366 days. Divide by 366 when someone asks how many leap-year-sized blocks fit in a span. 1,461 days is four Gregorian years including one leap day — 1,461/366 ≈ 3.99 of these blocks, which is why you should not use this as a date engine.

A 5K is 5,000 meters, not 5 kilometers on the nose if your watch is sloppy. Divide meters by 1,000. Track races, building plans, and “how far was that hike” all live in this split.
Feet to Meters
Unit Converters
US height, ceiling height, and lumber still arrive in feet. Meter plans do not. One foot is exactly 0.3048 m — not “about a third.” Use this when a listing says 10 ft ceilings and the architect works in meters.
Inches to Centimeters
Unit Converters
Monitor diagonals, waist measurements, and photo prints still come in inches. Clothing charts in Europe come in cm. Multiply inches by 2.54. That factor is exact, not a kitchen guess.
