This isn't so bad when you get the concept!

Metric is nice! When you get 1,000 of one unit, it's 1 of another! Or, if you have $\dfrac 1{1,000}$ of one unit, you have one of another.

So, here's the order:
1,000 nanoseconds (ns)
=
1 microsecond ($\mu$s)

1,000 microseconds ($\mu$s)
=
1 millisecond (ms)

1,000 milliseconds (ms)
=
1 second (s)

But you don't have to take it in steps.
For example,
$\rm1s = 1,000ms = 1,000,000 \mu s = 1,000,000,000ns$
This comes from "unit conversion." Please ask about that if you need!

It's easier to say that
$\rm 1s = 10^3ms=10^6\mu s=10^9ns$

It's a lot to take in, but you can see that it's still increasing by a factor of 1,000 each time...

Since $\rm1s=10^6\mu s$, you convert like before (I didn't show it, but ask if you want to see it)
$\rm0.00005s*1=0.00005s*\dfrac{10^6\mu s}{1s}=?$ The answer will be in $\mu\rm s$, see?

So, that number, 0.00005 will be 1,000,000 times larger. So, move the decimal 6 places to the right. Each place you move to the right is just like multiplying by 10! So multiply by 10 a total of 6 times. Move the decimal place to the right 6 digits.
