According to the Energy Star chart, 12,000 BTUs will cool a room of 450 up to 550 square feet. I'd stay on the low end of that.
80000
The rule of thumb is 2-1/2 tons per 1000 square feet. It is not measured in BTU which is a heating term
To cool a space of 400 square feet, you typically need around 20 BTUs per square foot, which totals approximately 8,000 BTUs. However, this can vary based on factors like ceiling height, insulation, number of occupants, and heat-generating appliances. For more precise needs, consider these variables and consult with a professional for an accurate assessment.
The number of BTUs in a 6 ft baseboard heater would depend on the model and specifications of the heater. On average, a 6 ft baseboard heater can generate around 1,000-1,500 BTUs per linear foot, so a 6 ft baseboard heater may produce approximately 6,000-9,000 BTUs.
About 1/3 of an acre.
Around a million. plus or minus a few.
Standard practice holds that it takes 5000 BTUs to heat a room 100 to 150 sq ft Figure on adding another 1000 BTUs for every 50 or so sq ft added. Hence , 400 to 450 sq ft would need about 10,000 BTUs
30000 btus for every 400 square ft
30000 btus for every 400 square ft
