EZ Currency Converter & Units

166 currencies, sci calculator

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

166 currencies updated daily, 224 units across 15 categories, plus a real engineering calculator with calculus. Works offline. No account needed. One app for the three conversions you actually need — travelling, working, studying. CURRENCY • 166 currencies, updated daily • See one amount in several currencies at once, updating live • Type an expression straight into the amount field: 1250×3 converts 3750 • Rates from open.er-api.com, with the European Central Bank as backup • Cached on device, so the last rates still work with no connection UNITS 15 categories, 224 units: length, weight, volume, area, speed, time, temperature, pressure, power, energy, data, density, angle, force, electricity. Includes units other converters skip — Taiwanese ping, jia, chi and jin, Chinese shi jin and shi mu, troy ounces, US dry and liquid measures kept properly separate. Temperature uses real formulas, not a ratio. ENGINEERING CALCULATOR Switch between basic and engineering mode. Engineering mode has five pages: • Functions: x^y, √, ∛, ⁿ√, |x|, n!, e^x, ln, log, log₂, mod, floor, ceil • Trig: sin/cos/tan, inverse, hyperbolic, inverse hyperbolic, degrees or radians • Discrete: nPr, nCr, gcd, lcm, AND/OR/XOR/NOT, bit shifts • Analysis: Σ series, Π product, derivative d/dx, definite integral ∫, mean, median, standard deviation, variance • Constants: π, τ, e, φ, plus 15 physical constants including the speed of light, Planck constant and Avogadro number Derivatives use central differences and integrals use adaptive Simpson — not lookup approximations. Bitwise results show hex, octal and binary side by side, with negatives in two's complement. Memory keys M+ / M− / MR / MC included. MORE • 20 languages, with currency names and number formats following your region • Dark mode • No sign-up, no account Privacy: no personal data collected. The amounts and expressions you type never leave your device.

Version 4.0 is a complete rewrite. Currency • 166 currencies, updated daily • Tap any currency on screen to make it the one you type in • The currency list is grouped by how commonly each one is used, so you are not scrolling past 166 names • Small amounts keep their precision: 1 JPY now shows as 0.006293 USD instead of 0.01 • Rates are stored on the device, so the app works offline Units • 224 units across 15 categories • Fixed incorrect conversion factors carried over from the old version Calculator • New engineering mode with over 60 functions, including derivatives, definite integrals, series, permutations and combinations, and bitwise operations • Hex, octal and binary shown together, with two's complement for negative numbers • Memory keys M+, M-, MR, MC • Fixed results being truncated to 6 decimal places Also • Redesigned throughout, with dark mode • 20 languages
