CSS Unit Converter

Giới thiệu về CSS Unit Converter

CSS Unit Converter helps front-end developers and designers translate measurements between the six most common CSS length units: px (pixels), rem (root em), em (local em), % (percent), pt (points), and vw (viewport width). Getting unit conversions right is critical for responsive layouts — a spacing value that looks perfect at a 1440px viewport can break completely at 375px if the units are not chosen carefully. rem and em are preferred for typography because they scale with the user's browser font size preference, improving accessibility; vw adapts to viewport width for fluid layouts; and px remains useful for borders and fine details that should not scale. Enter any value, pick its unit, and see all six equivalents computed simultaneously. You can also customise the base font size (default 16px) and viewport width for accurate context-specific conversions.
