Sous Vide Steak Safety. The FDA states that beef is safe when it is held at 130Â°F for over 112 minutes, or 140Â°F for over 12 minutes. This is very easy to do with sous vide and the main reason we recommend cooking most beef cuts medium-rare since beef is most tender at that temperature.
btu per pound * pounds per gallon   OK, it sounds as if you know the value of fuel in oil btu per pound.Now find out how much a gallon of fuel oil weighs and multiply the bâ¦tu value x that weight in pounds and that is the value per gallon. Or simply, diesel fuel is #2 fuel oil which contains 140,000 btu per gallon.
1 barrel of residual fuel oil = 6,287,000 Btu ; 1 cubic foot of natural gas = 1,037 Btu ; 1 gallon of propane = 91,333 Btu ; 1 short ton (2,000 pounds) of coal = 19,146,000 Btu (for the electric power sector) 1 kilowatthour of electricity = 3,412 Btu ; Examples of converting different energy sources to Btu. Example 1: You have a natural gas furnace in your home that used 81,300 cubic feet of natural gas for heating last winter. Your neighbor has a furnace that burns heating oil that used 584 gallons of heating oil last winter. You can convert the natural gas and heating oil consumption data into Btu to determine which home used more energy for heating.
