About Unit Converter
Unit conversion is one of the most common day-to-day tasks: converting miles to kilometers for a road trip, kilograms to pounds for cooking, Celsius to Fahrenheit for weather reports, or gigabytes to megabytes for storage planning. This tool covers 8 categories with dozens of units — length, weight, temperature, area, volume, speed, time, and digital storage. Every conversion happens in your browser, so it works offline and is instant. No signup, no ads interrupting, no data leaves your device.
How It Works
- Choose a category (Length, Weight, Temperature, Area, Volume, Speed, Time, Data).
- Enter a value and select the source unit.
- Choose the target unit — the result updates live.
- Use the swap button to reverse source and target instantly.

💡 Advanced Tips & Pro Insights
- ▸Temperature is special — Celsius, Fahrenheit, and Kelvin use different formulas (not simple multiplication), which this tool handles correctly.
- ▸For cooking, US cups (236.588 mL) differ slightly from metric cups (250 mL). This tool uses US customary units by default.
- ▸Digital storage uses binary prefixes (KiB = 1024 bytes) vs decimal (KB = 1000 bytes). This tool uses decimal (KB, MB, GB) unless noted.
- ▸For scientific work, remember that conversions are exact within the displayed precision — but always keep significant figures in mind.
- ▸For engineering or precision work, verify against your industry standard — some industries (e.g., oil & gas) use specialty units not shown here.
Frequently Asked Questions

Is my data safe?▾
Yes, 100% safe. All conversions happen in your browser. No values are sent to any server.
Which categories are supported?▾
Length, Weight, Temperature, Area, Volume, Speed, Time, and Digital Data. Each category has all the common units.
How accurate are the results?▾
Conversions use exact conversion factors (e.g., 1 inch = 2.54 cm exactly). Results are shown up to 10 significant digits.
What is the difference between US and metric cups?▾
US cup = 236.588 mL. Metric cup = 250 mL. This tool uses US customary units unless otherwise specified. For recipes, always check which convention the author used.
Is a KB 1000 or 1024 bytes?▾
Strictly speaking, KB = 1000 bytes and KiB = 1024 bytes. This tool uses the decimal (KB = 1000 bytes) convention for data, matching SI standards.
Can I convert between metric and imperial?▾
Yes. In the Length, Weight, Area, and Volume categories, both metric (m, kg, L) and imperial (ft, lb, gal) units are available and can be converted to each other.
Does it work offline?▾
Yes, after the page loads once, all conversions happen in your browser and continue working without internet.
