How to convert nanoseconds to milliseconds
To convert a measurement in nanoseconds to milliseconds, multiply the value by 0.000001. The conversion factor comes from the relationship between both units and the second.
For example, to convert 5 ns to milliseconds: 5 × 0.000001 = 0.000005 ms.
What is a nanosecond?
A nanosecond is one billionth of a second (0.000000001 s). Light travels about 30 centimeters in one nanosecond. The nanosecond is fundamental to modern computing; CPU clock cycles and memory access times are measured in nanoseconds. Grace Hopper famously illustrated a nanosecond as a ~30 cm length of wire.
Common uses of nanoseconds include: CPU clock cycles and memory latency; Fiber-optic and high-frequency electronics; Particle physics event timing; GPS signal timing and synchronization.
What is a millisecond?
A millisecond is one thousandth of a second (0.001 s). There are 1,000 milliseconds in one second. The millisecond became a practical everyday unit with the rise of digital electronics and computing, where events on this timescale (network pings, screen refreshes) directly affect user experience.
Common uses of milliseconds include: Network latency and ping times; Display refresh and input response times; Camera shutter speeds; Audio processing and synchronization.
Nanoseconds to milliseconds worked examples
Here are some common values converted:
1 ns = 0.000001 ms 5 ns = 0.000005 ms 10 ns = 0.00001 ms 50 ns = 0.00005 ms 100 ns = 0.0001 ms
Frequently asked questions
How many milliseconds are in one nanosecond?
One nanosecond (ns) equals 0.000001 milliseconds (ms). Multiply any value in nanoseconds by 0.000001 to convert to milliseconds.
How do I convert nanoseconds to milliseconds?
Multiply the value in nanoseconds by 0.000001. For example, 5 ns × 0.000001 = 0.000005 ms.
How do I convert milliseconds to nanoseconds?
Multiply the value in milliseconds by 1,000,000, or divide by 0.000001. Use the swap button on the converter above to reverse the direction.
Is the nanosecond to millisecond conversion exact?
Fixed units (second through week) are exact. Month and year use the average Gregorian calendar length (30.44 and 365.2425 days) since these vary in practice.
What is the formula for nanoseconds to milliseconds?
The formula is: ms = ns × 0.000001. This comes from the definition of both units relative to the second.
