1 therm unit equals 100000 btu's
Efficiency % = (Output/Input) x 100
2.5 tons. Whenever you see multiple digits digits together in a model #, any brand, the last 2 digits in the FIRST series of numbers is the btu output. So in this case you take the 30 out of nxh530gka100 and you have 30. ! ton of cooling is equal to 12,000 btus so 30 is 30,000 btus divided by 12,000 equals 2.5 Any questiions about HVAC contact John at shojohn@yahoo.com
We are calculating the response time of the ramp input signal (temperature), ramp rate is a Temperature varies linearly with time.
MBH [ thousands of BTUs per hour] is an expression for the rate of energy consumption or production: M is for thousands, B is for Btu's (Brittish Thermal Units) and H is "per hour" . ie: 860,000 Btu's per hour = 860 MBH
MBh stands for One Thousand BTU per hour. BTU stands for British Thermal Unit. MBh units should help with the cost estimate of running your air conditioning (AC). It's a measure of the heating/cooling capacity of AC equipment.MBH - One MBH is equivalent to 1,000 BTU's per hour. The 'M' is derived from the Roman Numeral M that equals 1000. Such as MMIX = 2009.(This M is often confused with the SI (Système International) 'M' which stands for the prefix Mega, equal to One Million (1,000,000). Note BTUs and therefore MBH are Imperial Units.)BTU - A standard unit of measurement used to denote both the amount of heat energy in fuels and the ability of appliances and air conditioning systems to produce heating or cooling. It is is the amount of heat required to increase the temperature of a pint of water by one degree Fahrenheit. BTUs are measurements of energy consumption, and can be converted directly to kilowatt-hours (3412 BTUs = 1 kWh) or joules (1 BTU = 1,055.06 joules). A wooden match produce approximately 1 BTU.

110 therms.
1.034 therms
divide the number of therms by 10,000 to get mmcf
1 BTU is 0.00001 therms.
1 million BTU = 10 Therms
The word deca- means ten, so there are ten therms in a decatherm.
Therms Natural Gas to CCF Natural Gas multiply by 0.9756
The answer depends on the material. The number of therms in liquid nitrogen is pretty close to 0.

With 28,000 BTUs, the Friedrich SL28L30* has the most BTUs.
