i had the same question
its usually about 20 btu's per square foot
350 pounds per square foot equals 1.71 metric tons per square meter.
One square foot
you cant really get a weight on a square foot basis, you need the thickness, steel generally weighs 495 lbs per cubic foot
Lumens and foot candles are not the same. A lumen is a measurement of the intensity of light, a foot candle is a measurement of lumens per square foot.
You need to mention the voltage and wattage of the device to get the right answer
A micathermic heater is used where there is not much space to place a conventional heater. They can be mounted on a wall like a picture which saves foot space.
A base board heater could be rated at any amount of watts. Their physical size usually has no bearing on the wattage but that being said usually the smaller the physical size the lower the wattage. A three foot unit at 240 volts could be 500 watts or .5 kW. The rating of the heaters is on the back of the heater. If the heater is mounted and you want to know how many watts it is, you will have to remove the heater away from the wall to get to the nameplate. If you have access to a clamp on amp meter, the amperage reading can be multiplied by the voltage of the heater. This will give you the wattage of the device. To find kW divide the wattage of the heater by 1000. The amount that the heater uses in kW s depends on its off and on time cycle. This is referred to as kWh. This is the figure that the utility company uses, times how much they charge for a kWh, to calculate the charge to you for the power that you have used.
In order to find the correct size space heater, first you need to find the AREA of the room, which is 10 x 12 = 120 square feet. Then you multiply this by 3.41 BTU's = 4092 BTU's. A STANDARD SPACE HEATER will be appropriate (a standard space heater is appropriate for up to 5100 BTUs or 1500 watts). If there are a lot of windows or the ceilings are higher than normal (normal is from 8 ft to 10 ft tall ceilings), than you may need a larger space heater, but in this case, a standard sized space heater will do.

Square footage is the base for rent for store space in many shopping malls. Some stores may have a premium per square foot base on location.
It depends on what kind of space heater you use. Each space heater includes specifications regarding how much heat it can throw and be effective in what size area. Read the labels to calculate how many heaters of a particular type would be effective in getting the basement to the desired temperature.
