This is a type mismatch since BTU (or at least the only BTU I know of), standing for British Thermal Unit, is a measure of heat energy, whilst cubic meters are a measure of volume.
It is possible to express energy as pressure x volume however:
1 BTU is approx 1055 Joules of energy => 1055 Pa/m2.
For more information on these two terms, take a look at:

Propane has a heat content of 19,900 btu/lb net. This means that a 36000 btu/hr heater needs to burn 1.809 lbs of propane per hour to produce this amount of heat. A 40 lb bottle will last about 22 hours if the heater runs continuously.
One BTU is equal to one degree Fahrenheit in the sense that it one BTU is the amount of heat required to raise a pound of water's temperature by 1 Degree Fahrenheit. BTU is short for British thermal unit.
15000 BTU/hr is equivalent to approximately 139,500 BTU/day. To convert this to Fahrenheit, you would need to consider other factors like the specific heat capacity of the material involved. Temperature is a measure of the average kinetic energy of the particles in a substance, which is different from the energy being produced by the 15000 BTU/hr.
A British Thermal Unit (BTU) is the amount of heat energy needed to raise the temperature of one pound of water by one degree F. This is the standard measurement used to state the amount of energy that a fuel has as well as the amount of output of any heat generating device. You might be able to imagine it this way. Take one gallon (8 pounds) of water and put it on your stove. If the water it 60 degrees F. and you want to bring it to a boil (212 degrees F.) then you will need about 1,200 BTUs to do this. All combustible materials have a BTU rating. For instance, propane has about 15,000 BTUs per pound. Charcoal has about 9,000 BTUs per pound and wood (dry) has about 7,000 BTUs per pound. This gives you an idea of how much fuel you'd need to, say, cook something. When it comes to gas grills they all have a maximum BTU rating per hour. If you see a 35,000 BTU gas grill that means that that grill puts out 35,000 BTUs from all its main burners combined in one hour, or uses a little more than 2 pounds of propane an hour. While the BTU rating on a gas grill doesn't necessarily tell you how much heat it will produce, it does give you an idea and it tells you how much fuel you'll be burning
It is a measurement of heat energy or the output of a heating or cooling device. A British Thermal Unit is the amount of energy needed to raise or lower the temperature of one pound of water by one degree F.
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.
Ther are 1,050 BTU in one cubic foot of natural gas.
To convert from cubic feet to mmBTU (million British Thermal Units), you need to know the energy content of the gas being measured, typically expressed in BTU per cubic foot. The general conversion formula is: mmBTU = (cubic feet × BTU per cubic foot) / 1,000,000. For example, if the gas has an energy content of 1,000 BTU per cubic foot, then 1,000 cubic feet would equal 1 mmBTU. Always ensure to use the correct energy content value for accurate conversions.
To convert cubic feet per hour (cfh) to BTU (British Thermal Units), you would need to know the heat content of the gas being used. If we assume natural gas with a heat content of 1,000 BTU per cubic foot, then 3000 cfh would be equivalent to 3,000,000 BTU per hour.
To convert Cubic Feet to Btu's, multiply by 1,000 1 CF = 1,000 Btu's
How to convert Cubic meter to BTU
2500 btu per cubic foot of vapor.
32 BTU = 24,901.416 foot-pounds.
One BTU per hour is equal to approximately 0.00029307107 kilowatts. To convert 25,000 BTU per hour to cubic meters, you first convert it to watts (25,000 BTU/hr = approximately 7,328 watts). Then you can use the power formula, Power (W) = Volume flow rate (m^3/s) * Density of air (kg/m^3) * Specific heat of air (J/kg*K) * Temperature change (K) to calculate the volume flow rate in cubic meters.
To convert foot-pounds per minute (ft-lb/min) to British thermal units per hour (BTU/hr), you can use the conversion factor that 1 ft-lb/min is equivalent to 0.00063241 BTU/hr. Simply multiply the value in ft-lb/min by 0.00063241 to obtain the equivalent value in BTU/hr.
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.
CMH is a unit of flow rate (m3/hr or cubic metres per hour) A BTU is a British Thermal Unit, a unit of energy that is equal to around 1055 joules. You cant convert the two as they are a measure of different things, but changing BTU (or Btu) to joules will help standardise the calculations.
