Every converter a professional reaches for, in one app. 36 categories, 198 units and 15 specialist tools that ordinary converter apps skip. Built for people who convert for a living: trades, engineers, designers, video editors, developers and cooks. And there is not a single ad in it. WHAT YOU CAN CONVERT โ€ข Convert length, weight, temperature, volume, area, speed and time โ€ข Work in pressure, torque, power, force, energy, density, flow and fuel economy โ€ข Check live exchange rates for 30 currencies, cached so they keep working offline โ€ข Match wire sizes with AWG to millimetre tables built for the job site โ€ข Run SMPTE timecode at every frame rate, drop frame handled correctly โ€ข Turn cups into grams for 25 real ingredients, with oven temperatures included โ€ข Compare time zones city by city and paste the result into a meeting invite โ€ข Convert colours across HEX, RGB, HSL and CMYK with contrast checks โ€ข Switch between binary, octal, decimal and hex with a 32 bit view โ€ข Calculate percentages, tips, discounts, date gaps and download times โ€ข Convert Roman numerals, paper sizes, Unix timestamps and more MADE FOR ACCURACY Conversion factors follow SI and NIST definitions, exact where an exact definition exists. Numbers stay monospaced while you type, results show sensible precision, and every tool works with no signal. SHARE THE ANSWER Every tool shares a clean text summary, so the person on the other end gets the conversion, the working and the source in one message.
