steam
We can convert electrical energy into mechanical energy in mixer and grinder. We can convert electrical energy into sound energy in various sound systems. We can convert electrical energy into heat energy in electric water or room heater.
Heat energy is, to an extent, unusable energy. If you have a heat DIFFERENCE, you can convert part of the heat energy - but only part of it - to other kinds of energy. That part, you can of course convert to practically any other type of energy.
Iron wire is a conductor of heat/electricity only and it is impossible to convert heat to electrical energy by using it.
Heaters (With Resistive Coils) will change Electrical Energy into Heat Energy. Electric Motors (AC and DC) will convert Electrical Energy into Motion Energy.
A dynamo converts rotational energy into electrical energy. A good example is one used on a bicycle to generate power for the lights.
One common method is for the heat to be used to generate steam in a turbine. The steam is allowed to escape from the turbine in specific directions. The force of the steam leaving in one direction causes an equal force which will move the turbine in the opposite direction. The rotational motion of the turbine is [rotational] mechanical energy. This energy can be used to drive machines which can convert the rotational action into linear action - if required.
Chemical energy from petrol which is converted to heat then to kinetic energy and then converted to rotational energy.

how can heat be turned into chemicals
Flashlights convert electric energy to light energy and heat energy.

Least what? Anyway, heat energy is in a way the least useful form of energy, because you can normally convert any other energy to heat energy, but if you have heat energy, you can no longer convert all of it back to other forms of energy.

Heat is defined as "energy in transit owed to a difference in temperature". The "internal energy" (or intrinsic energy) is the sum of the energy of all the atoms or molecules in a given body. In gases it includes the molecules or atoms kinetic energy (translation energy), rotational energy, vibrational energy, electronic energy... Solids lack the kinetic and rotational energies. Internal energy is thermal energy. So is heat, but heat is thermal energy in motion due to a difference in temperature.
