What is a Millisecond and a Fortnight?

A millisecond is a unit of time equal to one-thousandth (1/1,000) of a second.

A fortnight is a unit of time equal to exactly two weeks, which corresponds to 14 days or 336 hours.

Note: The Millisecond is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Fortnight belongs to the imperial/US customary system.

History of the Millisecond and Fortnight

The millisecond is derived from the SI base unit, the second, using the metric prefix 'milli-', indicating a factor of 10⁻³. Its common usage grew with the need for finer time measurements in science and technology, particularly in fields like computing and electronics.

The word "fortnight" originates from the Old English term "fēowertīene niht," meaning "fourteen nights." Counting periods by nights was common among ancient Germanic peoples. The term has been in continuous use in English for centuries and remains relatively common in the United Kingdom, Ireland, Australia, New Zealand, and some other Commonwealth countries, although its usage has declined somewhat in favor of "two weeks," especially in North America.

Common Uses for milliseconds and fortnights

Explore the typical applications for both Millisecond (imperial/US) and Fortnight (imperial/US) to understand their common contexts.

Common Uses for milliseconds

Computing: Measuring network latency (ping times), hard drive seek times, human reaction times in psychological tests, frame duration in video (e.g., 60 fps is ~16.7 ms per frame).
Audio: Measuring delays and processing times in audio signals.
Sports: Timing in races where differences are extremely small (e.g., swimming, track and field).
Science: Measuring short-duration events, such as the firing of a neuron or rapid chemical processes.
User Interface: Often used as a target for response times in interactive systems (e.g., aiming for under 100 ms for a feeling of instant response).

Common Uses for fortnights

Scheduling: Used in some regions for scheduling events, meetings, or appointments that occur every two weeks.
Payroll: Some companies, particularly in the UK and Australia, operate on a fortnightly pay cycle (paid every two weeks).
Publications: Certain magazines or journals might be published fortnightly (bi-weekly).
General Conversation: Used informally in regions where the term is common to refer to a two-week period (e.g., "I'm going on holiday for a fortnight").
Literary/Formal Contexts: Sometimes used in literature or more formal writing for stylistic reasons or historical accuracy.

Frequently Asked Questions

Questions About Millisecond (ms)

How many milliseconds are in one second?

There are 1,000 milliseconds in a second.

How many milliseconds are in one minute?

There are 60,000 milliseconds in a minute (1000 ms/s * 60 s/min).

Is a millisecond a long time for a computer?

In computing terms, a millisecond can be quite long. Processors perform millions of operations in a millisecond. Network latency is often measured in tens or hundreds of milliseconds.

About Fortnight (fn)

How many days are in a fortnight?

A fortnight consists of exactly 14 days (or 336 hours).

How many weeks make a fortnight?

A fortnight is equal to exactly 2 weeks.

Where does the word "fortnight" come from?

It originates from the Old English phrase "fēowertīene niht," which literally translates to "fourteen nights," reflecting an old practice of counting periods of time by the number of nights.

Is "fortnight" commonly used everywhere?

No, its usage varies significantly by region. It remains relatively common in everyday language in the United Kingdom, Ireland, Australia, New Zealand, and some other Commonwealth countries. However, in North America and many other parts of the world, the term "two weeks" is far more prevalent.
