If you’ve ever tried to spec heating wire for a project—whether it’s a small benchtop prototype or a full-scale industrial heater—you’ve probably bumped into a deceptively simple number: ohms per foot. It looks straightforward, but it has a huge impact on performance, safety, and cost. Get it right and your heater reaches target temperature smoothly and predictably. Get it wrong and you can end up with underpowered heat, blown power supplies, burned insulation, or a design that’s impossible to manufacture consistently. Ohms per foot is essentially a “resistance density” for…
