A 5000 BTU might give you a drop of 5 degrees C in a 6' x 8' office with no south facing windows, as long as the ceiling isn't too high. For a normal 10' square room, 12,000 BTU is a more reasonable starting point, then add more for sources of heat gain in the room.
It depends on your enviornment. A 36,000 BTU unit will probably work just fine. 36,000 btu's would heat a 1,000 square foot room. or more.

If measuring heat, a BTU measures the amount of heat that is required to raise the temperature of a pound of water to 1º Fahrenheit. In terms of air conditioning, the BTU determines the amount of heat the unit can remove from the room. As the BTU rating increases, so does the size, weight and cost of the unit.

Btu and cubic meter are two different measuring units. Btu is the unit for heat transmission, like in ac units 12000 btu/hr. It means this ac unit would remove 12000 btu of heat from the room in one hour. where as cubic meter is the unit for volume.
