## What is ConvertPro?

Get the measurement. Get the answer. Get back to work.

ConvertPro is a measurement toolkit for people who work with their hands — trades, technicians, makers and engineers. It opens on the converter, takes fractions the way you actually write them, and works with no signal at all.

FRACTIONS DONE PROPERLY
Type 7 3/8 and get 187.325 mm — not 187.3. Tap a fraction key instead of hunting for a decimal. Convert back the other way and see the nearest 1/2 through 1/64, with exact matches marked so a rounded fraction never pretends to be exact.

COMPOUND MEASUREMENTS
5' 8", 2 lb 8 oz and 2h 35m are single measurements, and ConvertPro reads and writes them that way. 68 inches comes back as 5 ft 8 in.

A KEYPAD BUILT FOR MEASURING
Big keys, a fraction slash, a space for mixed numbers, and one-tap fraction shortcuts. No fighting a phone keyboard for a slash.

BUILT FOR YOUR TRADE
Choose Construction, Electrical, Plumbing, HVAC, Woodworking, Mechanical, Engineering or Cooking — or several. The categories and tools you need come first.

PROFESSIONAL CALCULATORS
Concrete volume, flooring with waste, paint coverage, slope and grade, board feet, lumber sizes, Ohm's law, AWG wire gauge, voltage drop, pipe volume, duct airflow and recipe scaling.

Calculators are clearly marked as calculators. Each one states its assumptions, because an estimate is not a code compliance check.

ACCURATE ON PURPOSE
Imperial and metric conversions use the exact factors from the 1959 international yard and pound agreement — one inch is exactly 25.4 mm. Pressure, force, torque, power and energy follow SI definitions. Temperature converts affinely, so °C, °F, K and °R all round-trip exactly. AWG figures are computed from the defining formula rather than copied from a table. All of it is covered by an automated test suite.

WORKS OFFLINE. ALWAYS.
Every conversion, calculator, widget and Shortcut runs on your device. The unit database is inside the app. Airplane Mode changes nothing.

PRIVATE BY DESIGN
No account. No sign-in. No analytics, no advertising, no third-party SDKs, no tracking of any kind. Your measurements, history, favorites and projects never leave your device. Conversion history can be switched off entirely.

ALSO INCLUDED
• Widgets for the Home Screen and Lock Screen
• Siri Shortcuts and App Intents that convert without opening the app
• Favorites, searchable history and projects
• Search that answers "10 ft to m" as you type
• Full VoiceOver, Dynamic Type, Reduce Motion and Voice Control support
• Light and dark themes, both deliberately designed
• English, French and Spanish

FREE FOREVER
Length, area, volume, mass, temperature, speed and time conversions. Favorites, history, offline use, and the fraction tool. No ads, and no limit on how much you convert.

CONVERTPRO PRO — ONE PAYMENT
Every trade mode, all seventeen professional tools, the advanced categories (pressure, torque, flow, density, viscosity, thermal and the full electrical set), projects, advanced precision and fraction denominators, and the widgets. Bought once, not rented. Family Sharing included.
