Everyone, my name is ahmad ali in this question.

He wants us to convert a unit of three converting mathematically statements.
00:10
The first one we want to write 28 .9 nanometer.
00:16
We want to write it to micrometer.
00:22
To write this we have to weigh.
00:25
The first way, we will write the number normally 28 .9.
00:31
And remove nano and about 10 negative 9 meter.
00:38
Then if we want this number decrease so this decimal will move in this direction.
00:46
So we won't write 8 negative 6.
00:52
So it will be removed 3 times.
00:56
Here 1, here to here 3 so it will be 0.
00:59
0 .0, so 1, 2, 3, 289 times a byte, negative 6 meter.
01:16
And here we can write it 0 .029 micrometer...
