Here let’s pull a number out of our butts, let’s say a drop is a sphere with a diameter of 5mm, so the radius is 0.25cm. Volume is 4/3 pi r^3 which comes out to 0.065 cm^3/ drop.
0.294/0.065 gives 4.5 drops.
So you’d need 5 drops of gasoline to get your days worth of energy.
Seems we’re off by a factor of a thousand. Most likely you doubled up on 1Calorie = 1000 calories. (Damnit food industry, what the hell?!?) 1kcal is already converted to the base calorie, as opposed to 1kCal.
Hmmm let’s see, you need roughly 2.39kcal or 10kJ of fuel a day.
Gasoline has an energy density of 45 MJ/kg.

Sciencing those together means you need 0.00022 kg or 0.22g of gasoline a day
Gasoline has a mass density of 0.7475 g/cm^3, more sciencing means you need 0.294 cm^3 of gasoline by volume.

You are correct!
big Calories are conventionally uppercase, while small calories are conventionally lowercase. So 1 Calorie = 1000 calories = 1 kcal.
Stupid naming system, I know.
