How can I specify exactly 600px width in Tailwind CSS

Question

There are numerous width tools in the Tailwind Official Docs that we can use.

However, w-96, or width: 24 rem, is the widest fixed width I can define (384px)

At first glance, I thought I could use w-600px, but it turns out that it is exactly 1px. I spotted a strange class named w-px.

There will be many odd widths I need to mention because I am now transferring my old project to Tailwind CSS; however, Tailwind CSS does not automatically offer them.

Would it be wonderful if I could just do w-600px, or am I missing a better strategy?
