Nissan Motor Co. said it has developed a new type of paint that significantly reduces the temperature inside vehicles parked in direct sunlight.

The surface of a car coated with the innovative material remains up to 12 degrees cooler than that of a vehicle with standard paint, tests showed.

The company said the coating material can help rein in the temperature rise not only on the car's body but also in the vehicle when exposed to direct sunlight.

Why would it be anything else?

It's clearly too low a number to be °K. And since the only two valid units of measurement for temperature are Kelvin and Celsius, it must be °C.

A differential temperature of 12C is equal to a differential temperature of 12K….. You don’t take the offset into account for differential temperatures.
