Heat (temperature converter)

Convert temperatures with only a few touches! Heat converts between Fahrenheit and Celsius with a simple, intuitive interface that can be easily used by anyone who's spent fifteen minutes with an iPhone or iPod touch. Its big, readable displays are clearly visible at arm's length and in direct sunlight. Heat also supports Kelvin and Rankine, two temperature units used in science and engineering. It includes a built-in four-function calculator, perfect for, say, subtracting 5°F from 30°C.

Heat is a free app based on Converter, the most popular paid unit converter in America and a top 100 paid app in nearly twenty countries. If you're thinking about getting Converter but aren't sure yet, Heat is the perfect way to take it for a test drive--or if you only need to convert temperatures, Heat gives you something you'd otherwise have to buy for free.
