Viewport units size things relative to the window, 100vw is the width, 100vh is the height, and they are what make full-screen sections actually full-screen. Converting px to them by hand is pointless math.
Convert px to vw, vh, vmin, and vmax at a given viewport size. Use the result for scalable type and hero sections, and keep the fixed pixels for borders and details that should not breathe with the window.
