WireSizer vs Convertizo

WireSizer is the fast, accurate, and easy-to-use DC wire size calculator for choosing the correct wire gauge every time. Simply select your DC voltage, current, and total circuit length with flips of your finger. No keyboard required. WireSizer instantly calculates the correct wire gauge for the Voltage Drop percentage you need. WireSizer is ideal for: • Boats and marine electrical systems • RVs, trucks, and cars • Radios and electronics • Solar power and battery-based DC systems • Any low-voltage DC system up to 60 VDC Suitable for both professionals and DIY users. WireSizer automatically calculates the minimum wire size required for your circuit (assuming copper wire), taking Voltage Drop into account for installation and temperature conditions. Results are checked against current-carrying capacity (ampacity) limits to prevent using unsafe undersized wire. Supported values: • Voltage up to 60 VDC • Current up to 500 amps • Total circuit length up to 600 feet or 200 meters • Voltage Drop 1 to 20 percent • AWG wire 18 gauge to 4/0, plus 250 & 300 kcmil • SAE wire 18 gauge to 4/0 • Metric wire 0.75 mm² to 150 mm² WireSizer allows you to fine-tune calculations based on real-world installation conditions: • Engine compartment or other high-temperature environments • Sheathed, bundled, or conduit-run wire • Wire insulation ratings from 60°C to 200°C WireSizer also includes a Materials List so you can record and review all of your wire selections in one place. WireSizer calculates DC wire sizes in accordance with ABYC E-11 (July 2025). For typical low-voltage DC circuits, results generally correspond with ISO 13297:2020. Results are a design aid; final wire selection and installation compliance remain the installer's responsibility. Number and decimal formatting will follow your device's regional and language settings. WireSizer works without an internet connection and contains no ads. Designed exclusively for DC circuits - not for use with AC circuits. Results are a design aid. Final wire selection and installation compliance remain the installer's responsibility. WireSizer will cost you less than the wire scraps you probably throw away at the end of the day.

Convertizo turns everyday conversions into a simple calculator for iPhone and iPad. Enter a number and see the result instantly. Convert currency, length, area, volume, weight, temperature, speed, time, data, energy, power, pressure, angle, flow, frequency, and torque. Pick up where you left off. Convertizo remembers your last category and saves your most recent value and unit pair for every category. Frequently used categories and units move to the top of their selection lists automatically, while the category grid stays alphabetical. Tap or hold a numeric value to copy it. Tap the input value to paste a number using the standard iOS edit menu. Search unit lists by name or symbol, or swap the source and destination with one tap. Currency rates use daily European Central Bank reference rates. Saved rate data keeps currency conversions available when you are offline. All other conversions run on your device. Convertizo includes: • An alphabetical grid of 16 conversion categories • A single-screen calculator with large circular keys • A compact category menu with your frequent choices first • Searchable unit lists that remember your frequently used units • Native copy and paste • Your most recent value and units saved for every category • Decimal and binary data units with precise large-number results • Country flags for currencies • A layout designed for both iPhone and iPad Your conversion history and usage preferences are stored on your device.
