What is a Millisecond and a Microsecond?

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

A microsecond is a unit of time equal to one-millionth (1/1,000,000) of a second. It is also 1/1000th of a millisecond.

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

History of the Millisecond and Microsecond

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 microsecond is derived from the SI base unit, the second, using the metric prefix 'micro-', indicating a factor of 10⁻⁶. Its use became prevalent with the advent of electronic computers, radar technology, and high-speed photography.

Common Uses for milliseconds and microseconds

Explore the typical applications for both Millisecond (imperial/US) and Microsecond (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 microseconds

Computing: Measuring instruction execution times in older processors, interrupt latency, bus transfer times.
Physics: Duration of certain chemical reactions, some nuclear events, timing in particle accelerators.
Electronics: Defining pulse widths in digital signals, measuring signal delays in circuits.
Biology: Duration of nerve impulses, time scale for certain enzymatic reactions.
Everyday: The flash duration of a typical camera strobe is a few microseconds.

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 Microsecond (μs)

How many microseconds are in one second?

There are 1,000,000 (one million) microseconds in a second.

How many microseconds are in one millisecond?

There are 1,000 microseconds in a millisecond.

What does the symbol μs mean?

The symbol 'μ' (mu) is the Greek letter used as the metric prefix for micro (10⁻⁶), and 's' stands for second.
