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.
The scientific consensus is that unless otherwise stated it’s Celsius.
In scientific papers you just write 14° you don’t need to specify the unit.
So I’m just going to use that rule and assume Celsius.
