WHAT YOU CAN CONVERT โข Convert length, weight, temperature, volume, area, speed and time โข Work in pressure, torque, power, force, energy, density, flow and fuel economy โข Check live exchange rates for 30 currencies, cached so they keep working offline โข Match wire sizes with AWG to millimetre tables built for the job site โข Run SMPTE timecode at every frame rate, drop frame handled correctly โข Turn cups into grams for 25 real ingredients, with oven temperatures included โข Compare time zones city by city and paste the result into a meeting invite โข Convert colours across HEX, RGB, HSL and CMYK with contrast checks โข Switch between binary, octal, decimal and hex with a 32 bit view โข Calculate percentages, tips, discounts, date gaps and download times โข 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.
