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

How is the Mac app different from the free iOS version?
Both share the Mila's Tools engine. The Mac edition is a one-time paid download optimized for desktop workflows — larger layouts, drag-and-drop favorites, and native macOS keyboard input.
Does it work offline?
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?
Yes. Enter mixed units like 5 feet 7 inches or 2 pounds 4 ounces — the app normalizes and converts all related units automatically.
Is there a free Mac version?
Unit Converter: Mila's Tools is free on iPhone, iPad, and Mac through a separate App Store listing. This paid Mac title targets users who want the full desktop experience as a standalone purchase.
