Question

How do I write 15 milli 'anything' in decimal form? .0015 or .00015?

Answer 1

If you're talking about how many millimeters are in a meter, there are 1000 mm in one meter. This makes the measurement of 15 mm .015 meters. The same goes for milliliters to liters, milligrams to grams, etc.

Answer 2

'milli' = 1/1000 = one-thousandth = 0.001

So, 15 'milli' something = 15 * 0.001 = 0.015

Answer 3

Milli anything means times 10 to the negative 3rd power.  Consequently 15 milli "somethings" = 15 x 10 to the negative 3rd power "somethings" = .015 "somethings".

Answer 4

Ummmm, you're wrong BOTH TIMES

"milli-" equals one thousandth (1/1000).

Using meters for an example:

One millimeter = 0.001 meter

0.001 meter x 1000 = 1 meter (so you can see that a thousand of them equals one whole unit)

If you use meters for example, and you start with one millimeter, multiply it by 15 to get 15 millimeters, as follows:

0.001m = 1 millimeter

0.001m x 15 = 0.015m = 15 millimeters

15 millimeters is also written as 15mm

You can substitute any standard of measurement instead of meter, whether it is liters, degrees, or whatever you are trying to do.
