Everyday Calculators

ArrayKit's everyday calculators handle the small day-to-day jobs — work out a GPA or the grade you need on a final, plan a bedtime around sleep cycles, convert units like length, weight and temperature, translate shoe sizes between countries, roll dice or estimate a golf handicap. Each calculator runs entirely in your browser, so the details you enter stay on your device and nothing is uploaded. They give quick, practical answers with no setup, so you can get on with your day.
