One converter instead of five apps.
How many centimetres in an inch? How many grams in a cup of flour? Which exchange rate to trust? Which cable will carry the load? How much will a loan really cost?
The answers are in one app, and almost all calculations work offline.
Over 50 sections and 800 units
Length, mass, volume, area, speed, temperature, pressure, energy, power, time, angles, density, viscosity, electrical quantities, radiation, illuminance, data storage, number systems and more.
Sections are arranged in groups, and search covers sections and units at once. Inches, pounds and cups can be typed and shown as fractions — 1 5/8.
Currencies from 14 sources
Over 180 currencies and cryptocurrencies. Rates come from 14 sources: the central banks of Russia, the Eurozone, Ukraine, Belarus, Poland, Moldova, Transnistria, Kyrgyzstan, Israel, Turkey, and crypto exchanges.
You decide which sources to trust: switch off the ones you don't need and move the ones you do to the top. Downloaded rates stay available offline.
Cooking converter that knows density
A cup of flour and a cup of honey weigh differently. Over 190 products: convert grams to cups, spoons and millilitres and back — density is taken into account automatically.
Cable sizing by IEC, NEC and PUE
Choose a conductor or check an existing one: current, line length, installation method, temperature, voltage drop. The calculation follows the chosen standard, and the app shows which requirement was decisive. A table of ampacities is included.
Battery pack builder
Enter one cell's parameters and an S×P layout — the app calculates the whole pack: voltage, capacity, energy, current limit and cell count. Presets for Li-ion, LiFePO₄, LiPo and NiMH.
Solution and gas concentration
Solutions: mol/L, g/L, mg/dL, % w/w, normality — for 74 substances, from blood test analytes to lab reagents; solution density is filled in for you. Gases: ppm, mg/m³ and percent LEL for 30 substances. Plus water hardness and glycated hemoglobin (HbA1c).
Loan calculator with early repayments
Payment, overpayment and total cost update as you type. Three schemes: annuity, declining payments or interest only.
Add fees, expenses and early repayments — the app shows the monthly schedule, remaining balance, savings, new term and effective rate.
Ship tanks
Cargo volume and mass from the vessel's calibration table: sounding or ullage, trim correction, fill percentage. Tables are entered in the app or loaded from a file.
Coordinates without manual parsing
Copy a pair of coordinates from a map and paste it — the format is detected automatically. Degrees (55.7558°), degrees and minutes (55°45.348′) and degrees, minutes and seconds (55°45′20.88″) convert into each other on the fly.
Clothing sizes and linked quantities
42 size tables: clothing, shoes, hats, gloves and belts for men, women and children. Combined sections link quantities by formulas: Ohm's law, fuel consumption with fuel price, battery runtime. Fill in the fields you know — the section calculates the rest.
Missing a unit? Create your own
The builder creates your own converters with any units and calculations. Define a relation by an equality or a formula — the app derives the inverse itself. Start from a built-in section and save the result to a file.
Make it yours
Add sections to favourites, hide units you don't need, reorder them, set your own abbreviations and choose their style — international (cm, kg) or local. Choose which screen opens at launch.
Usually need just one conversion? Turn on simple mode: two fields instead of a long list. Values are copied and pasted with a long press, and in Temperature the same gesture inserts a reference value — melting and boiling points of 39 substances.
And more
Light and dark themes, nine interface languages, adjustable rounding precision, tablet and landscape support.
Can't find a unit or calculation? Write to the developer: much of the app was added at users' request.
