Convert a straightener's temperature setting between units.
About Hair Straightener Heat
Temperature settings are often shown in Fahrenheit, and the Celsius conversion allows comparison with tools that display metric units. Heat damage depends on how hot the plates get, so knowing the true temperature helps choose the lowest setting that still smooths hair.
