microsecond to millisecond - How to convert µs to ms
If you ever needed to convert microseconds to milliseconds, you know how vital precise timing can be. Whether it’s for science, computing, or engineering, accuracy matters — and the difference between a µs and an ms could mean success or failure in critical tasks.
What is a Microsecond (µs)?
A microsecond is 1⁄1,000,000 of a second. That’s one millionth of a second — so short that light travels about 300 meters in this time. Microseconds are essential in electronics, telecommunications, and high-speed computing, where events happen faster than the blink of an eye.
What is a Millisecond (ms)?
A millisecond is 1⁄1,000 of a second — still very short, but much longer than a microsecond. Audio latency, gaming performance, and mechanical response times are often measured in milliseconds, making it a more human-related time scale while still precise.
How to convert microsecond to millisecond
To convert µs to ms, simply divide the microsecond value by 1,000.
Time (ms) = Time (µs) ÷ 1000
Example:
5000 µs ÷ 1,000 = 5 ms
This means that every 1 millisecond equals 1000 microseconds.
Suppose you need to perform this conversion quickly and accurately. In that case, you can try our Time Converter or explore more options in our Conversion Tools — both work for many time units, not just microsecond to millisecond.

Microsecond fact: In modern high-frequency trading, stock prices can shift in under 300 µs. Traders spend millions to reduce network latency by even a few microseconds.

Millisecond fact: In competitive online gaming, a 10 ms ping advantage can be the difference between winning and losing in reaction-based matches.
A Race Against Microseconds and Milliseconds
On July 20, 1969, NASA’s Apollo 11 lunar module, Eagle, was approaching the Moon’s surface. Astronaut Neil Armstrong realized the planned landing site was littered with boulders. He took manual control, guiding the lander toward a safer area.
The onboard Apollo Guidance Computer processed navigation and thruster commands in microseconds. Each millisecond counted as Armstrong maneuvered, balancing fuel consumption with descent speed. In fact, the module had less than 30 seconds of fuel left when it touched down. That’s less than 30,000 milliseconds — a razor-thin margin in spaceflight.
Without the precise conversion and synchronization between microsecond-level computer processing and millisecond-level human reaction, the landing could have ended in disaster. This historical moment remains one of the clearest examples of why time conversion — even between such small units — can be life-or-death important.
From Space Missions to Your Smartphone
From the Moon landing to your mobile apps, microsecond to millisecond conversions play a role in everyday life. GPS systems use microsecond timing to calculate your exact position. Smartphones process tasks in microseconds but display responses in milliseconds for human perception. The smooth scrolling on your screen, the lag-free video calls, the quick response in your favorite game — all rely on timing precision.
