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
A US gallon of water is about 8.4 lb, so 30,000 galls is 252,000 lb. One BTU is the heat to raise one pound of water by one degF, so BTU's in your example are 252,000 x 15 = 3,780,000 BTU.
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.
To convert mega joule per kilogram (MJ/kg) to Btu per pound (Btu/lb), you can use the conversion factor of 1 MJ/kg = 430.923 Btu/lb. Simply multiply the value in MJ/kg by 430.923 to get the equivalent value in Btu/lb.
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.
I think a Google search will help you with this one. Try: horse manure/btu or something like that.
It takes 970.4 BTUs to convert 1 lb of water at 212°F to 1 lb of steam at 212°F. This process is known as the latent heat of vaporization.
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

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.
0.29308323563892147 watts per btu there for 5200 btu = 1524.0328253223915 watts 1 watt=3.412Btu/hr 1 Btu=the amount of energy needed to heat 1 Lb of water 1 degree. A gallon of water weighs aprox. 8 Lbs.
divide price by 2.2 kg/lb
A 25000 BTU heater consuming at full capacity will typically last about 160 hours on a full 100 lb tank of propane. However, this estimate can vary based on factors like outdoor temperature, heater efficiency, and usage patterns.
