Wire Gauge Calculator °

Now with Voltage Drop Calculator! The fastest way to check wire size, ampacity (NEC 310.16), and voltage drop percentages. Essential for every electrician's phone.

Headline: The essential toolbox for electricians and engineers. Instant AWG conversions, NEC reference, and Voltage Drop calculations.

Body: Wire Gauge Calculator ° is a professional-grade utility designed for electricians, engineers, and DIY enthusiasts. Upgrade your workflow with a fast, modern, and offline-capable tool that replaces cumbersome charts and manual formulas. Whether you are sizing wire for a home renovation, checking a long cable run for voltage drop, or converting AWG to metric, this app provides instant answers based on standard electrical codes.

KEY FEATURES: Professional AWG Tool Instant Reference: Scroll through standard sizes from 18 AWG to 4/0 AWG. Metric Conversion: Automatically converts AWG to Diameter (mm) and Area (mm²). Max Load Capacity: Built-in ampacity lookup based on NEC Table 310.16 (Copper, 75°C). No internet required.

Voltage Drop Calculator (New in v1.1) Ensure your electrical runs are safe and compliant. NEC Compliance: Automatically alerts you if voltage drop exceeds the recommended 3% limit (Green/Red status indicators). Flexible Inputs: Quick-fill buttons for standard voltages (12V, 24V, 120V, 240V) or enter custom system voltages. Dual Units: Support for both Feet and Meters length inputs. Precise Formula: Uses standard resistance formulas (Copper) to calculate exact Voltage Drop (V) and Percentage (%).

Built for iOS Clean Interface: Native SwiftUI design that is fast and responsive. Haptic Feedback: Feel the confirmation when calculations complete. Privacy First: No data collection, no ads, works 100% offline.
