Milliseconds to seconds formula

s = ms ÷ 1000

Take the value in milliseconds.
Divide it by 1000 (the number of milliseconds in one second).

Example: 1,500 ms ÷ 1000 = 1.5 s.

Reverse formula (seconds to milliseconds): ms = s × 1000. Example: 0.5 s × 1000 = 500 ms.

The factor is a whole number (1000), so this one is easy to do in your head or with long division.

About milliseconds and seconds

Milliseconds (ms). A millisecond is one thousandth of a second. Reaction times, ping and animation timings are measured in ms.

Seconds (s). The second is the SI base unit of time, defined by the caesium-133 atomic clock frequency.

Frequently asked questions

How many seconds are in a millisecond?

One millisecond equals 0.001 seconds. Looking at it the other way, one second is 1,000 milliseconds.

How do you convert milliseconds to seconds?

Divide the number of milliseconds by 1000. For example, 1,500 ms ÷ 1000 = 1.5 s.

What is 500 milliseconds in seconds?

500 ms is 0.5 s (half a second).

How much is 1,000 milliseconds in seconds?

1,000 milliseconds equals 1 seconds.

How do I convert seconds back to milliseconds?

Multiply by 1000, or press the ⇄ swap button above. For example, 0.5 s × 1000 = 500 ms.

How do I read decimal hours?

The decimal part is a fraction of an hour, not minutes: 1.5 hours is 1 hour 30 minutes and 2.25 hours is 2 hours 15 minutes. Multiply the decimal part by 60 to get minutes.
