Btu / scf = Btu / lb X MW / 379.5
where:
MW = molecular weight of the gas, lb / lb-mol
The constant 379.5 is the molar volume at standard conditions of 14.696 psia and 60°F
Multiply (dollars per lb) by 2.20462. If you don't need it quite that accurate, multiply (dollars per lb) by 2.2 The formula to convert kg to lbs 1 kg* 2.2046 lbs 1 kg = 2.204622622 lbs
1 pound = 0.45359237 kilograms
3.99$/1lb * 1lb/0.453 kg = 8.80$/kg
Probably simplest (easiest not to get mixed up) to convert both to lb, subtract, then convert back to tons. 1 ton = 2000 lb, so: 6t 300 lb = 6x2000 lb + 300 lb = 12000 lb + 300 lb = 12300 lb 2t 900 lb = 2x2000 lb + 900 lb = 4000 lb + 900 lb = 4900 lb 12300 lb - 4900 lb = 7400 lb convert back to tons: 7400 lb/ 2000 lb per ton = 3 tons 1400 lb
Multiply the $50 by 2.2.... $50 per lb = $110 per kilo
You need to look at a steam table first then Multiply lbs/hr steam x latent heat of evaporation in BTU/lb @ the operating pressure.
It takes 1 BTU to raise 1 lb of water per degree Fahrenheit.
The latent heat of fusion for ice is 144 BTU/lb. For one ton, that is 2000 lb x 144 BTU/lb, or 288,000 BTU. Refrigeration's roots are in the ice making industry, and the ice guys wanted to convert this into ice production. If 288,000 BTU are required to make one ton of ice, divide this by 24 hours to get 12,000 BTU/Hr required to make one ton of ice in one day.
I think a Google search will help you with this one. Try: horse manure/btu or something like that.
There is approx 100,000 BTU per gallon of propane. A 100 lb propane tank holds approx 23 useable gallons. So that is 2,300,000 BTU. If the heater ran constantly burning 25,000 per hour that would be 92 hours straight.
Two pieces of information are require to answer this question.1BTU = 1055.05585J and 1kilogram = 2.2046226 poundsHence 1 BTU/pound = 1BTU/pound x 2.2046226pounds/kilogram x 1055.05585J/BTUor 1BTU=2326.00J/kgor 1BTU=2.326kJ/kgor 1BTU=2.326x10-3MJ/kgFor example if u need to convert 10500 BTU,10500BTU=10500BTU x 2.326x10-3MJ/kg10500BTU=24.42MJ/kgThe trick to conversion calculations is to always makes sure the unwanted units are cancelled with the ones you do want.

You can't-lb per cubic foot is a measurement of pressure, tonnes is measure of weight. You could convert Ib per cubic foot to tonnes per cubic foot or more usually, gram per cubic centimetre but not lb per cubic foot to tonnes
Multiply (dollars per lb) by 2.20462. If you don't need it quite that accurate, multiply (dollars per lb) by 2.2 The formula to convert kg to lbs 1 kg* 2.2046 lbs 1 kg = 2.204622622 lbs
Roughly 24 Megajoules per kilogram-it obviously varies in quality. 1 MJ = 947.8 BTU. 1 kg = 2.2 lb. So in US units, calorific heat of coal = 10,340 BTU/lb
1 pound = 0.45359237 kilograms
divide price by 2.2 kg/lb
