When do you need kWh → BTU?
Food labels in kJ, fitness in kcal, electricity in kWh, air conditioning in BTU — energy units link diet and bills. For example: a 330 ml cola has about 591 kJ ≈ 141 kcal; 1 kWh = 3,600 kJ; a 30-minute run burns roughly 300 kcal.
Where do kWh and BTU come from?
SI anchors to the joule. The kilocalorie = 4.184 kJ (from water-heating experiments); 1 kWh = 3.6 MJ is power × time; the BTU (1,055 J) persists in HVAC.
FAQs
▸How many BTUs is 1 kilowatt-hours?
1 kilowatt-hours equals 3,412.13 BTUs. Calculated as 1 × 3,412.13 = 3,412.13.
