2,500 calories = ~9.914 BTU
To convert calories to British Thermal Units (BTU), you can use the conversion factor of 1 calorie = 0.003968 BTU. Simply multiply the number of calories by this conversion factor to get the equivalent amount in BTU.
One barrel of crude oil contains approximately 159 liters. Given that one barrel provides six million Btu, this translates to about 37,688 Btu per liter (6,000,000 Btu / 159 liters). To convert Btu to calories, note that 1 Btu is approximately 252 calories, so one barrel provides about 1.51 billion calories. Therefore, per gallon (approximately 3.785 liters), crude oil provides about 142,000 calories (1.51 billion calories / 3785 liters).
