None, for the following reasons:
First, there is no such thing as a meli meter - perhaps you mean millimetre, which is a measure of length. Let us assume that you made a spelling error.
A decimal can either be 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. In that case, it is a pure number and has no dimensions of length and, according to the basic rules of dimensional analysis, conversion from one to the other is not valid.
Alternatively, a decimal is a measure of area, used mainly in South Asia. This has dimensions of Length2 and since that is different to the dimensions for a millimetre, again according to the basic rules of dimensional analysis, conversion from one to the other is not valid.
If you mean millimeter (mm) - There are 10mm per 1cm
