We're asked to convert 612 grams to milligrams.
00:06
And the prefix millie stands for 10 to the negative third.
00:13
And so if we know kind of the conversion of the prefix, we can just simply multiply by a factor of 10 to convert.
00:27
So we can start by doing 612 times, i'll do a different color, 612 grams times 10 to the negative third equals, and that's going to be the milligrams there.
00:45
Oops, milligrams.
00:49
But to just do this in standard scientific notation, we might want to change that a bit.
00:56
We might actually want to just go ahead.
01:00
We can actually just do this in our heads because 10 of negative third is 0 .001.
01:13
0 .00.
01:15
Yeah.
01:16
0 .001.
01:18
And so we can just go ahead and change this to 0 .6 .1.
01:24
We just move the decimal place over 1, 2, 3.
01:26
And we have this as aren't milligrams.
01:30
So it's mainly just an effort of moving the decimal place, however many places we needed to convert.
01:38
So that's 0 .612 milligrams.
01:43
And the next question, we're asked to do meters to centimeters, and centi means 10 to the negative second.
01:52
So this would be 8 .160 times 10 to the negative 7 .2.
01:58
Second.
01:59
That's seven centimeters.
02:01
And we can move the decimal place over, negative means twice, so we'll get 0 .08160 centimeters.
02:12
Now micro here, micro means 10 to the negative 9th.
02:17
So to convert from micro to grams, we need to multiply by 10 to the negative 9th.
02:27
And that's going to be quite a lot of decimal places.
02:31
Actually, excuse me, 10 of the negative 6.
02:33
My bad, 10 of the negative 6.
02:35
And so we are going to move the decimal place over 6.
02:41
1, 2, 3, 4, 5, 6.
02:43
So we'll have 2 0 .033779 grants.
02:51
That's not a lot.
02:53
Now we're going to do milliliters, 2 liters...
