Everyday conversions, not a unit museum
Searchers want cm ↔ inches, kg ↔ pounds, °C ↔ °F, liters ↔ gallons, and similar desk/travel/kitchen jobs. DevDock covers those six families with the units people actually use — complete enough to feel reliable, without drowning the page in obscure options.

FAQ
Which units are included?
Length, weight, temperature, volume (US kitchen + metric), area, and speed — the conversions people search for most. Obscure scientific units are left out on purpose.
Are volume units US or UK?
Cooking and liquid volumes use US measures (cup, fl oz, pint, quart, gallon). Metric milliliters and liters are included too.
Is temperature converted correctly?
Yes. Celsius, Fahrenheit, and Kelvin use the proper formulas (not a simple multiply), including absolute zero handling through Kelvin.
Is my data uploaded?
No. Conversions run entirely in your browser.
Can I convert currency?
No. Exchange rates change constantly and need live data. This tool is for physical units only.
