Energy & Power Converter

⚡ Energy & Power Converter - calories and horsepower on one screen The 200 kcal on a nutrition label. The 840 kJ on the same label in Europe. The kWh on your electricity bill. The 64 PS in a Japanese car brochure and the 47 kW in the European one. The 7,500 BTU/h on an air conditioner. Energy and power get written in a different unit in every field. Type a number once and see all of them side by side. 【9 energy units】 J (joule) / kJ (kilojoule) / MJ (megajoule) cal (calorie) / kcal (kilocalorie) Wh (watt-hour) / kWh (kilowatt-hour) BTU (British thermal unit) / ft·lbf (foot-pound) 【6 power units】 W (watt) / kW (kilowatt) / MW (megawatt) PS (metric horsepower) / HP (mechanical horsepower) / BTU/h 【Quick reference table】 Enter a value and every unit in that category is converted at once. You get more than "how many kJ is 200 kcal" - you also see it in watt-hours and BTU at the same time. 【PS and HP are not the same】 There are two horsepowers: PS (metric, 735.5 W) and HP (mechanical, 745.7 W). The same "200 horsepower" differs by about 1.4% depending on which one the brochure meant. Japanese and European cars are quoted in PS, American cars in HP. The app opens on PS to kW, so you can just type the number in. 【Simple to use】 1. Pick Energy or Power 2. Type a number 3. Tap the unit you are converting from, and the unit you want Tap "⇅ Swap" to reverse the direction in one step. 【Presets for common values】 A day of food, a bowl of rice, a microwave oven, a small air conditioner, the Japanese kei car power limit. One tap fills in the value. 【History of the last 5 conversions】 Tap any entry to bring it back. History is stored only on your device and can be cleared at any time. 【Notes on the units】 Short explanations: why the calories on a label are really kilocalories, why PS and HP differ by 1.4%, how an air conditioner's kW rating relates to BTU per hour. The notes also cover the fact that there is more than one calorie - nutrition uses 4.184 J, engineering often uses 4.1868 J. This app uses the nutrition value throughout. 【Good for】 • Moving between kcal and kJ on nutrition labels • Imported hardware rated in BTU or HP • Converting a car's PS figure into kW • Comparing air conditioners rated in kW and in BTU/h • Seeing what a kWh of electricity is worth in calories 【Japanese and English】 The app follows your device language. Nothing to configure. 【No account needed】 The conversion runs on your device, and the figures you type are never sent anywhere. 【Privacy Policy】 https://cof745.github.io/enerugi-privacy/ 【Contact】 [email protected]
