There are 12000 btu`s in a ton, so divide your total heat gain by 12000 for tonnage.
OK
18000 BTU means TON 1.5 ,12000 BTU means 1 TON
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.
Square feet has nothing to do with how much an X BTU heater can heat, heat is calculated by determining how much heat LOSS there is to make up for. AC is the exact opposite, it's size is determined by how much heat GAIN there is. In general, a 120,000 BTU boiler can heat an average well insulated 2 story house, no problem. There are many programs that calculate heat loss/gain but since there are people who do it for a living, try asking one.
