Engineering Tools
Free, client-side tools for quick calculations. We built these because opening a heavy CAD program just to check a voltage drop is a waste of time.
Voltage Drop Calculator
Calculate drop over distance for DC circuits.
Bundle Diameter
Estimate the physical thickness of a bundle.
AWG to mm²
Convert American and metric wire gauges.
Current Capacity
Estimate max amps based on wire size/temp.
Bend Radius
Safe flex limits for wire bundles.
Harness Weight
Estimate total kg of a harness.
Wire Resistance
mΩ resistance factoring length & temp.
Fault Current
Estimate short-circuit amps for fuses.
Twisted Pitch
Lay lengths for CAN/data lines.
Fuse Sizing
Derate fuses based on load and ambient temp.
