Unitova: Convert & Calculate

Unitova brings unit conversion, professional calculation and live market tools into one clear, offline-first workspace. 77 categories, 540+ units and more than 60 calculators, all searchable from a single box. CONVERT WITH CONFIDENCE • 77 categories and 540+ units: length, area, volume, mass, pressure, energy, power, speed, data, angle, fuel economy and many more. • Type "km to mile", "kg", "m2" or a misspelled word — the search finds units, symbols and tools instantly. • Swap units in one tap; tap a result to see full precision. • Save units and unit pairs as favorites and keep results in history. BUILD, MEASURE, ESTIMATE • Area of rectangles, triangles, circles, polygons and irregular plots from coordinates. • Metal weight for 12 materials and 9 profile shapes, plus IPE, HEA and angle catalog weights and cut lists. • Concrete, paint, tiles, flooring, bricks and blocks, plaster, screed, drywall, roofing, insulation and rebar quantities. • Room and parcel projects: floors, walls, openings, waste and cost lists saved as local workspaces. • Volume and tank capacity with liquid mass; stairs, slopes, ramps and roof pitch. ENGINEERING AND SCIENCE • Electrical: Ohm's law, AC single/three-phase power, resistor colour codes, series/parallel networks, LED resistors, RC time constant, voltage drop. • Mechanical: gear and pulley ratios, torque–speed–power, springs. • Fluids and HVAC: pipe flow, pressure loss (Darcy–Weisbach/Colebrook), pump power, multi-section pipelines, air changes, duct velocity and duct pressure networks, psychrometrics, heat loss. • Thermal: heating energy, conduction, expansion, R/U values, heat exchanger LMTD. • Chemistry: molar mass from formulas, equation balancing, stoichiometry, molarity, dilution, ideal gas, limiting reactant. • Acoustics, optics and photography, image and print sizing, paper and textile calculations. EVERYDAY TOOLS • Percentages, ratios, unit price comparison, fuel cost, energy cost, motion and pace, data transfer time. • Discounts, VAT, tips, margins, loans and interest, recipe scaling, work time, time zones, business days, age and dates, adult BMI. LIVE MARKET VALUES • Currencies, cryptocurrencies, precious metals and monthly commodities with cross conversion. • Gold section: gram, quarter, half, full and Ata coins plus the troy ounce, with 24/22/18/14 carat, a quantity field, and a premium check that compares a dealer's quote with the pure-gold value. • Every value shows its source and data time; offline you see the last saved data and its date. MAKE IT YOURS • Define your own formulas with named variables and unit-bound inputs. • Compare two saved results side by side. • Export history and project workspaces to PDF or CSV, or copy and share a single result. BUILT TO STAY CLEAR Direct navigation, readable text and focused work screens. Numeric fields open the right keyboard, example values act as hints, and every calculator explains its assumptions and limits. On tablets and in landscape the tool list stays beside the workspace. Dark theme, high-contrast option, large-text support and screen-reader labels throughout. Full interface translations: English, Turkish, German, Spanish, French, Arabic, Portuguese (Brazil) and Italian. Unitova has no ads. All Pro features are free for the first 15 days; afterwards a Basic set stays free and monthly, yearly or lifetime Pro unlocks everything. Fixed conversions and local calculations work without internet. Live market values need a connection to refresh. Market information is for calculation and informational purposes only and is not financial advice. Engineering results are preliminary estimates and do not replace codes, standards or professional judgement.
