A new kind of calculator that takes units seriously. Add kg, km/h, kcal to your numbers and just multiply or divide. 60 km/h × 2 h correctly gives you 120 km. 1 kWh ÷ 1 h = 1 kW works naturally too. Trying to add unrelated units like 3 kg + 5 m? The app politely stops you and offers to switch to multiplication with one tap. You catch the mistake and move on instantly. Length, mass, energy and data results are also compared with familiar things: 210 kcal shows "banana ~ 2 ×", 4.7 GB shows "DVD ~ 1 ×". Numbers regain their meaning. Features - Launches with the leading unit of the active category preselected (Mass: kg) - 9 categories: Mass, Length, Time, Volume, Area, Temperature, Speed, Data, Energy - SI base units + Celsius/Fahrenheit + binary data units (KiB, GiB) - Imperial units (in, ft, yd, mi, lb, oz) and US cooking measures (gallon, fl oz, cup) - Japanese cooking measures (cup, tablespoon, teaspoon) - Tap "No unit" to use it as a regular calculator - Smart blocking of dimensionally invalid calculations - Scale comparison cards for length, mass, energy and data results - Available in 16 languages "If you can't measure it, you can't understand it."
