About this app

ConverTool is a fast, clean unit converter. Type a number and every result updates as you type: no "Convert" button, no system keyboard covering the screen. Just a calm, paper-and-ink design made for one hand.

WHY CONVERTOOL
• Results as you type: the target value and every other unit in the category update with each key.
• Its own keypad: digits, decimal point, ±, backspace and swap, always at the bottom of the screen.
• Search: find any unit by name or symbol (psi, inch, oz) and jump straight to it.
• Pinned pairs: keep the conversions you use most, like °C → °F or kg → lb, on the home screen.
• Recent conversions: your latest pairs, one tap away.
• Exact definitions: "1 in = 2.54 cm · exact" right under the result. Every factor is taken from its official definition (SI, NIST, BIPM, international agreements).
• Readable numbers: your language's decimal separator and digit grouping, ×10ⁿ for very large or very small values, and 4, 7 or 10 significant digits.
• Copy and share: copy the result with one key, or share the conversion.

18 CATEGORIES, 240+ UNITS
Length · Area · Volume · Mass · Temperature · Time · Speed · Fuel economy · Pressure · Energy · Power · Force · Torque · Angle · Data · Data rate · Density · Kitchen

• Common units come first; specialist units wait under "More units".
• Data done right: kB, MB, GB (1000) and KiB, MiB, GiB (1024) are separate units.
• Fuel economy and running pace convert properly: L/100 km, km/L, mpg (US and UK), minutes per km and per mile.

KITCHEN, CLEARLY MARKED
Cups, glasses and spoons to millilitres, and to grams for 24 ingredients such as flour, sugar, butter, rice, milk and honey. Ingredient weights come from USDA FoodData Central. Because they depend on how the cup is filled, kitchen results are always marked as approximate (≈), and approximate values never appear in the other categories.

PRIVATE, WORKS OFFLINE
No account, no sign-up. Conversions work without an internet connection. Your pinned and recent pairs stay on your device: only the units, never the numbers you type. The app shows a small, non-personalised banner ad.

Light and dark themes. 12 languages: English · Türkçe (Turkish) · Kurdî – Kurmancî (Kurdish) · Azərbaycan dili (Azerbaijani) · Kiswahili (Swahili) · Español (Spanish) · Português (Portuguese) · Français (French) · Deutsch (German) · Русский (Russian) · Bahasa Indonesia (Indonesian) · Italiano (Italian).
