To be a stickler, communication requires respect for your audience. The vast majority of everyone understands a 1.8 degree C delta. I would argue that very few people anywhere would understand a temperature delta given in kelvin.

How is expecting readers to not understand what a kelvin is respecting the audience?

		You misread. Most people do not understand temperature on the Kelvin scale. As such, you should not use it to communicate in a general setting such as this.

		The same way expecting you understand what a Kelvin is isn't respectful to you.
