Converters
Convert between 150+ currencies, engineering units, and everyday measurements with visible conversion factors.
35 tools available
Converting between units shouldn't feel like a chore. These converters cover length, weight, volume, temperature, pressure, energy, force, power, angle, fuel efficiency, density, and thermal properties — all using standardised conversion factors with proper attention to precision and edge cases. Whether you're converting PSI to bar for an engineering spec or Celsius to Fahrenheit for a recipe, the results are instant and the maths is visible. No server calls, no data collection, just straight conversion.
The most commonly used converters — Length, Weight, Volume, and Temperature — handle everyday tasks like recipe conversions, travel measurements, and international unit differences. The Temperature Converter is particularly useful for cooking: it converts between Celsius, Fahrenheit, and Kelvin with offset and scale adjustments handled correctly (not just a linear formula, which breaks at extreme values).
For technical work, the Pressure Converter handles PSI, bar, Pascal, atmospheres, and mmHg — critical for engineers working across metric and imperial hydraulic or pneumatic systems. The Data Storage Converter translates between bytes, kilobytes, megabytes, gigabytes, terabytes, and their binary equivalents (KiB, MiB, GiB), which matters when provisioning cloud storage or comparing drive capacities where manufacturers use decimal but operating systems use binary.
The Currency Converter pulls exchange rates and handles over 150 currencies with proper rounding rules. The Number Base Converter supports binary, octal, decimal, hexadecimal, and arbitrary bases up to base-36 — useful for developers debugging memory dumps or network packets.
All converters display the conversion factor used, so you can verify the result or apply the same factor in your own calculations.
How to choose the right tool
Match the converter to your precision needs. The basic Length, Weight, and Volume converters handle everyday tasks. For engineering work, use the Pressure, Energy, or Force converters which handle more units and show the conversion factor.
Watch the Data Storage Converter for cloud provisioning — manufacturers use decimal (1 GB = 1,000 MB) but operating systems use binary (1 GiB = 1,024 MiB). The tool shows both so you can compare accurately.
Common use cases
- Engineer working across imperial and metric — The Pressure Converter handles PSI, bar, Pascal, and mmHg with visible conversion factors for verification.
- Cook following an international recipe — The Temperature Converter correctly handles the offset and scale between Celsius and Fahrenheit at extreme values.
- Developer provisioning cloud storage — The Data Storage Converter shows both decimal and binary units so you can compare manufacturer specs with OS-reported capacity.
