From

Century

A century equals 100 Julian years. Used in historical, cultural and archaeological contexts. The 21st century covers 2001–2100 technically, though popular usage often treats 2000–2099 as the 21st.

Real-world: The 20th century = 1901–2000. A century-old building. Modern human civilisation spans tens of centuries.

Millisecond

The millisecond equals 0.001 second. Essential in computing, networking and high-speed photography. Human reaction time is about 200–300 ms. Video frame rates of 60 fps correspond to a 16.67 ms per frame.

Real-world: Ping to a local server: 5–20 ms. Game frame at 60 fps: 16.67 ms. Human reaction: 200–300 ms.

Tips & common mistakes

Quick tips

1 century = 100 years = 36,525 days.
Ordinal numbering: 21st century = 2001–2100 (strict), 2000–2099 (popular).
Rarely useful in engineering — years or decades are more practical.

Avoid these

Writing 20th century when meaning 1900s — they overlap but differ in first/last year.
Treating century exactly as 100 × 365 days — ignores leap years.
Mixing calendar systems (Gregorian vs. Julian) across centuries — matters pre-1582.
