Unit Conversions

Convert units with confidence. Built by a professional engineer to respect your time and help you stay focused.

FEATURES

• 60+ unit categories and 2300+ units

From everyday conversions (length, volume, temperature, currency) to less common ones (pressure, energy, power, torque) to engineering and scientific units (dynamic viscosity, surface tension, thermal conductivity, mass flow rate, and more)

• Three converter views

Dropdown for quick conversions, checkbox list for comparing two units, or comprehensive view showing all units at once

• Formulas shown

See the math behind the conversions. Great for homework or verifying calculations

• Customizable

Enable only the categories and units you need. Set significant figures, gauge pressure reference, standard gas flow conditions

• Currency support

Updates rates automatically when online, or set rates manually. Shows the rates being used

• Works offline instantly

All conversions happen locally

• Search

Find units and categories quickly. Searches filter to your selected category

• Dark and light themes

• Multiple languages

WHY THIS APP EXISTS

Built out of frustration with unit converters that lack engineering units. Built with the desire for a positive user experiences.
