Is it really better for day to day life? I am certain that it only appears so because you're used to it. I think for day to day life they're both roughly equivalent.

Of course, for me Celsius is more natural and intuitive, but again - that's because I'm used to it.

Kelvin is superior for science and engineering but doesn't arbitrarily anchor the scale to the freezing and boiling point of water in the way Celsius and Fahrenheit both do.

273.15 Kelvin doesn't roll off the tongue like 0°C or 32°F.

>Better for day to day life

It is not.
