You will need to give more information. The Btu's of baseboard is determined by the water temperature and the type and size of the element. Copper fin tube (copper pipe with aluminum fins over it) heats up quick and loses heat quickly it also has many diameters of element (copper tube). Most common in residential is 1/2", 3/4" & 1" ID (the OD will be 1/8" or so larger). There is also Cast iron baseboard that heats up slowly and cools off slowly (this is a much more even and comfortable heat). You should never mix and match cast iron radiation and copper radiation of the same circuit it will cause large temperature swings in conditioned area. Tell us what the boiler temperature is set to and what the type of radiation is and you'll get an answer.

to calulate your btu needs,you can use this link: http://hearth.com/calc/btucalc.html
You need 100W per square meter. 100W equals around 341.3BTU. 1 square meter are around 10.7 square feet. You therefore need around 32 BTU per square foot.
A 12,000 BTU heater is needed for a 1,400 square foot area. BTU or British Thermal Unit is a unit of measure commonly used for heating and cooling.

Most output ranging from 560 to 600 btuh per foot, this is with 170 F water temps. I have no way to know your specifics from where I am.
10 ft by 10 ft --- a 4 ft baseboard heater will work. But a longer room may need more. 10 ft by 20 ft would need an 8 foot baseboard heater. etc.
about 12,000
$1.50 / lenear foot
It depends on the climate and how well your home is insulated.A good rule of thumb is about 20 BTUs per square foot.
You can get this information the same place you get the heaters. You will need to give them information on the size and dimensions for your home.
its usually about 20 btu's per square foot
1 standard cubic foot of natural gas gives about 1030 BTU
30000 btus for every 400 square ft
30000 btus for every 400 square ft
There are about 1030 BTUs in a cubic foot of natural gas. If one wishes to know the gas consumption (in feet3 per hour) for a given BTU per hour usage rate, one would divide the amount of BTUs by 1030. That would yield the number of cubic feet of gas that is used per hour. Q: I'm heating a space using 10,300 BTUs per hour and I'm using my natural gas heater to do it. How many cubic feet of gas am I using per hour? A: 10,300 BTUs (the heat generated per hour) divided by 1030 (the number of BTUs per cubic foot of gas) equals 10 cubic feet. You're using 10 cubic feet per hour. You apply 10,300 BTUs to heat the space per hour, and you use 10 cubic feet of gas per hour to do that. (And yes, I picked easy numbers.)
A standard 4 foot baseboard heat will consume 1000 watts/1Kilowatt. So if you could calculate how many hours per day/week/month you can multiply the hours by power consumption and getKWh(Kilowatt Hours) per month.
