This energy converter helps you switch between common energy units used in science, home appliances and electricity consumption estimates.
Frequently Asked Questions
1 calorie (thermochemical) equals 4.184 joules. To convert joules to calories, divide by 4.184. For example, burning 500 kcal (kilocalories) in a gym session equals 2,092,000 joules or 2,092 kJ. Food energy labels in India use kcal — a typical 100g serving of rice is about 130 kcal or 544 kJ. Physics textbooks in India use joules, so this conversion helps bridge lab work and nutrition studies. Use the free Energy Converter on AbacusHand to calculate your exact result instantly.
1 kWh (kilowatt-hour) equals 3,600,000 joules (3.6 MJ). This is important for understanding electricity consumption. A 1 kW electric kettle running for 1 hour uses 1 kWh = 3.6 million joules of energy. A 100W light bulb running for 10 hours also uses 1 kWh. This conversion helps students and engineers calculate energy efficiency and understand how electrical work relates to mechanical energy in the SI system.

Indian electricity bills measure consumption in kWh (units). 1 unit = 1 kWh = 3.6 MJ. If your bill shows 300 units consumed in a month, that is 300 kWh of energy. At ₹6 per unit (average residential tariff in India), 300 units cost ₹1,800. A 5-star AC rated at 1.5 kW running 8 hours daily consumes 12 kWh per day = 360 kWh per month. Understanding kWh helps compare appliance energy consumption and estimate bills. Use the free Energy Converter on AbacusHand to calculate your exact result instantly.
A typical Indian meal (2 rotis + dal + sabzi) provides roughly 400–500 kcal. To burn 400 kcal, a 70 kg person needs approximately 45 minutes of brisk walking or 30 minutes of running. 1 kcal = 4.184 kJ. A 500 ml bottle of a sweet beverage (about 200 kcal) requires about 20–25 minutes of jogging to offset. Fitness apps in India like HealthifyMe display energy in kcal — converting to kJ helps compare with scientific literature. Use the free Energy Converter on AbacusHand to calculate your exact result instantly.
1 megajoule (MJ) equals 0.2778 kWh. So 10 MJ = 2.778 kWh. This conversion is relevant in solar energy — India receives about 4–6.5 kWh/sq m/day of solar radiation. A rooftop solar panel of 1 kW capacity generating 5 kWh per day produces 18 MJ of energy daily. Solar project reports in India often present data in MJ or GJ, while household understanding is in kWh.
