102,000 BTU = 1 ccf
Typically, use 5 * the volume in cubic feet to get BTU/hour for natural gas heaters. For this shop, that works out to 180,000 BTU/hr. Lower ceilings would make a big difference here...
The answer to this depends on the cost of natural gas. In my area, natural gas is about $11 US per 1000 Cubic Feet or basically 1.1 cents per cubic foot. At the same time, electricity in my area is 10.9 cents per kilowatt hour. Neither of these costs include taxes and customer charges so the actual cost is actually higher. To answer the question though, one kilowatt is the equivalent of 3416 Btu. One cubic foot of natural gas has 1030 Btu per cubic foot. So we need 3416/1030 or 3.3 cubic feet of natural gas. At 1.1 cents per cubic foot that is 3.63 cents of natural gas. Now if you were using these to heat water, an electric heating element transfers about 98% of it's energy to the water. A natural gas heater only transfers about 65% of it's energy to the water while the rest goes out the flue pipe. So the 1 kilowatt of electricity transfers 3348 Btu to the water. To get the same heating with natural gas would require 3348/.65 or 5150 Btu of natural gas. So 5150/1030 is 5 cubic feet or 5.5 cents of natural gas. Still considerably cheaper than using electricity in my area.
Oil has the higher BTU rating Depends. If it is Liquified Nat. Gas then it has the higher rating.
one cubic feet = 1028 Btu
To calculate the BTU requirement for a load of 560 cubic feet per hour (CFH), you need to consider the type of gas being used. For natural gas, the typical conversion is about 1,000 BTUs per cubic foot, so a 560 CFH load would require approximately 560,000 BTUs per hour. For propane, the conversion is higher, around 2,500 BTUs per cubic foot, resulting in a requirement of about 1,400,000 BTUs per hour. Always consult specific conversion factors for the exact gas in use to ensure accuracy.
Ther are 1,050 BTU in one cubic foot of natural gas.
1 cubic foot of natural gas can be burned to generate about 1000 btu of heat. A 105000 btu/hr appliance would therefore require about 105 cubic feet of natural gas per hour; this is 0.1 thousand cubic feet, or 0.1mcf/hr.
Natural gas varies in its composition from one source to another. Consequently, the answer will vary.
1 Therm is 100,000 BTU, and as there are 1000 BTU in 1 cubic foot of gas, 1 Therm = 100 cubic feet. Density of methane = 0.72 kg/cubic meter which is 35.3 cubic feet, so 100 cubic feet = 2.04 kg
The energy content of natural gas is typically measured in cubic feet (cf) in the United States and in cubic meters (Nm3) in other countries. One cubic foot of natural gas produces approximately 1,000 BTU (British Thermal Units) of energy. Therefore, 1 Nm3 of natural gas is roughly equivalent to 35,315 BTU.
One thousand cubic feet of gas (Mcf) -> 1.027 million BTU = 1.083 billion J = 301 kWh
The heat content of natural gas is typically measured in British Thermal Units (BTU) per standard cubic foot. The range can vary but it's commonly around 1,000 BTU per cubic foot. When calculating BTU per square foot, you would need to factor in the gas consumption rate to determine the BTU output for a specific area.
Specifically 1013.2 btu per standard cubic foot, for pure methane.
One Cubic Meter of natural gas is approximately 36000 btu.
Roughly, yes. Actually it is slightly more. A cubic foot of natural gas has approximately 1000 btus of heat energy when burned. Figures range as high as 1017 btu/cu.ft. based on the proportions of the mixed gases, primarily methane and propane, which have different heating values. The more propane the more heat in a cubic foot. A generalization made by gas distributors is that a hundred cubic feet [ccf] is equal to one therm [ 100,000 btu] of heat.
BTU should be a measure of heating content, so it will vary with composition. However, in the US, 1 cubic ft of natural gas = 1,028 BTU. 1 therm = 100,000 BTU 100 cf = 0.1 Mcf approximately 1 therm (th). or more exactly 0.0972 Mcf = 1 th. See natural gas under wikipedia.
The BTU (British Thermal Unit) rating of natural gas typically ranges from 950 to 1,100 BTUs per cubic foot. This measurement indicates the energy content of natural gas and is used to determine its heating value.
