It isn't clear what you want to convert. I suggest you ask another question, specifying from what you want to convert, and into what.
No. Energy has an ASSOCIATED mass. There is no such thing as mass-to-energy conversion, or energy-to-mass conversion. In a nuclear reaction, for example, BOTH mass and energy are CONSERVED. For a more detailed explanation, check the Wikipedia article on "binding energy".
mass of any substance to moles

Mass and energy are equivalent, so there are exchanges of between mass and energy any time there is a change in motion (kinetic energy). But Atomic energy is the most familiar conversion of mass into energy. The explosion of an nuclear bomb, or the energy generated by a nuclear reactor are consequences of conversion of mass into energy. Energy from combustion is not primarily derived from mass/energy conversion, but from exothermic chemical reactions. In fact, any such exchange between mass and energy would operate in the other direction, as gasses gain mass as they are put into motion (increased kinetic energy=increased mass). But any such gain is so tiny as to be meaningless.
There can be no conversion. A kilogram is a measure of mass. A millilitre is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid. The masses of equal volumes of the two substances will clearly be very different. So there is no direct conversion between mass and volume: you need to know the density of the substance to enable you to carry out the conversion.
Yes. The simplest conversion is F=Ma, or force equals mass times acceleration.
It can be used as a conversion factor.
The quantity that serves as a conversion factor between mass and number of moles is the molecular mass.
A milligram is a measure of mass and, as far as I am aware, data time is not measured as a mass. Consequently, conversion between the two is not valid.A milligram is a measure of mass and, as far as I am aware, data time is not measured as a mass.

False
No. Furthermore, there can be no conversion. A gallon is a measure of volume whereas a pound is a measure of mass. According to elementary dimensional analysis, conversion from volume to mass is not valid.
There can be no standard conversion. A milligram is a unit of mass. A liter is a unit of volume. For a specific substance, you can do the conversion if you know its density (mass = volume x density).
Milligrams measure mass, micro-litres measure volume. No direct conversion is possible
