These are three different forms of expressing a volume of 2000 ml:
2 liter
2. * 10³ ml
2. * 10⁰ liter
Explanation:
The expression 2000 ml means 2000 mililiters and convey three important informations:
The unit, which is mililiter (1 ml = 1 / 1,000 liter)
The magnitude, which is 2000
The precision: the zeros to the right of the figure 2 are not significative, so this magnitue is precise only to the thousands units. This means, that the measure could be between 1500 and 2499 (ml).
You might express the same volume with a different unit, e. g. liter, and in a different way (using scientific notation).
1) Changing the unit.
To change ml to liter you must multiply for the conversion factor:
1 = 1 liter / 1,000 ml
Thus, 2000 ml is equal to:
2000 ml * 1 liter / 1,000 ml = 2 liter
2) Using scientific notation:
You change the number to a power of ten, using a decimal greater than or equal to 1 and less than 10.
For 2000 the decimal is 2. and the power of ten is 3 (for the three zeros after the 2):
2000 ml = 2. * 10³ ml
2. * 10⁰ liter
