Centuries to Years Converter
years = centuries × 100.
A 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.
Centuries
c → yr
100 yr
0.5 century → 50 years. 2 centuries → 200 years.
- You typed

Frequently Asked Questions
A named century (19th) is a label. This is a count of 100-year blocks.

- Cat Years to HumanFirst year ~15, second ~9 more, then about 4 human years per cat year. Indoor cats often outlive the meme. Indoor/outdoor and dental care move this more than the formula.
- 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 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.
- Decades to YearsA decade is 10 years. The year on this site is the Julian year of 365.25 days used in astronomy, so a decade is 3,652.5 days, not “ten calendars plus guesswork.” History decades (1990s) are labels, not durations.
- Dog Years to HumanNot ×7. A common veterinary sketch: first year ~15 human, second adds ~9, then ~5 per year. Giant breeds age faster; tiny ones slower. This is a conversation starter, not a lifespan forecast.
- Julian Years to SecondsA Julian year is 365.25 days × 86,400 s = 31,557,600 s. Light-years, orbital periods, and IAU constants use this, not 365 or 365.2425. A millisecond of a Julian year is still a lot of seconds if you expand it.

Unit Converters
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.

Very usable on mobile. Would love a save/export option later, but the math feels solid.
