Loxley Unit Converter

Convert units. That's it. Pick a category, type a number, read the answer. No ads, no sign-up, no accounts, and nothing watching what you do.

Eight categories sit across the top: Length, Weight, Temperature, Volume, Area, Speed, Time, and Data. Tap a tab, choose what you're converting from and to, and type your value. The result updates as you type. There's a swap button to flip the two units, and each category remembers what you were doing when you switch between them.

Want to know how the number was reached? Tap "Show formula" and it lays out the math, including the worked steps for temperature (like °F = (°C × 9/5) + 32). Results are rounded to six significant figures, and numbers outside that range fall back to scientific notation so the answer stays readable.

The units are the ones you actually use: millimeters to miles, grams to pounds, Celsius/Fahrenheit/Kelvin, US cups and gallons, square feet and hectares, knots and miles per hour, milliseconds to weeks, and bytes to terabytes.
