Ambient temperature refers to the temperature of the surrounding environment. It's often used in contexts like:
* Climate control: 65 degrees might be a target temperature for a building's air conditioning or heating system.
* Electronics: Electronic devices often have an operating temperature range, and 65 degrees might be within that range.
* Weather: 65 degrees might be a pleasant outdoor temperature in many places.
Without more context, it's impossible to say exactly what "65 degrees ambient" means. Is it Fahrenheit or Celsius? Is it referring to a specific location or situation?
To understand the context, you'd need more information.
