About Mila's Tools: Unit Converter
Spreadsheets and browser tabs are slow ways to convert units. Mila's Tools: Unit Converter is a native macOS app with 300+ units across 29 categories — length, weight, cooking, blood sugar, fuel economy, and more — in one window that converts as you type.
Built for Mac, not a web wrapper
This is the paid Mac edition of the Mila's Tools converter family. It runs as a desktop app with category-specific themes, dark mode, comfortable or compact layouts, and quick-copy values — the same precision workflow iPhone users know, tuned for a keyboard and trackpad.
29 conversion categories
- Cooking, length, weight, volume, temperature, area, and pressure
- Energy, speed, time, power, force, frequency, and torque
- Density, angle, fuel economy, flow rate, and capacitance
- Illuminance, bits & bytes, blood sugar, dates, and fractions
- Numbers, slope, shoe sizes, ring sizes, and data transfer rates
More than basic unit math
- Compound units — enter feet and inches, pounds and ounces, or gallons and quarts; values auto-normalize (type 13 inches, see 1 foot 1 inch)
- Date calculator — days, weeks, months, and years between dates; shortcuts like “90 days from today”
- Fractions and numbers — fractions to decimals and percentages; Roman numerals, binary, octal, and hexadecimal
- Historical units — ancient Egyptian, Mesopotamian, Greek, Roman, and Biblical length measures
- Favorites — star and reorder the categories and units you reach for daily
- Precision control — automatic smart formatting or manual decimal places from 0 to 10
Frequently asked questions

- Yes. Every conversion runs locally on your Mac with no internet required.
- Can I hide units I never use?
- Yes. Show or hide any unit in any category, and switch between comfortable and compact view styles.
- Does it support compound measurements?
