Under the Privacy and Electronic Communications Regulations, anything that is not strictly necessary for the service you asked for needs your consent before it is set. On this site that means analytics, and nothing else.
Accepting and rejecting are offered the same way, in the same place, at the same size. Rejecting changes nothing about how the site works, and you are not asked again after you have chosen.

Turning them off in your browser
Every browser lets you block or delete cookies from its settings. Blocking the strictly necessary ones will sign you out and make the tool forget which unit you type in, but nothing will break.
How your personal data is handled more generally is set out in the privacy notice.
