What is a Microsecond and a Millisecond?

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.

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

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

History of the Microsecond and Millisecond

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.

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.

Common Uses for microseconds and milliseconds

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

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.

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).

Frequently Asked Questions

Questions 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?
