A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. If it does not contain a fractional part then the decimal representation does not require a decimal point. So the decimal for 20 ml is 20 ml. If you want it as a decimal fraction of some other quantity then you need to specify that second quantity.
