What is 7 microseconds per day?

7 microseconds per day is like having a tiny, super-slow timer that only ticks 7 times every full day.

Imagine you have a clock that ticks really slowly, so slow that it takes an entire day for it to tick just 7 times. That’s what 7 microseconds per day means!

What's a microsecond?

A microsecond is one millionth of a second. To picture this, think about how fast you can blink your eyes, that's pretty quick! But a microsecond is even faster than the blink of an eye.

If you had to wait for just 1 microsecond, it would be like waiting for the blink of an eye in a super slow movie, really, really slow!

How does this work over time?

If your timer only ticks 7 times in one whole day, then after a year, it would have ticked about 2,555 times. That's still super slow, like watching a snail crawl across the screen of a phone.

So 7 microseconds per day is just a tiny bit of time passing, really, really slowly!

Examples

  1. A clock that gains 7 microseconds every day might be off by a second in about 18 years.
  2. Imagine a race where each runner gets 7 extra seconds every day, it would change the results over time.
  3. If you had a timer that counted up by 7 microseconds every single day, after a year it'd have counted over 2.5 thousand of them.
