Convert a pixel value into a percentage of its container.

In web development, choosing the right unit for sizing is crucial for creating responsive and adaptable layouts. **Pixels (px)** are an absolute unit, meaning their size is fixed regardless of the screen size or browser window. A `250px` element will always be 250 pixels wide. This is great for elements that need a precise, fixed size, such as a logo or an icon.
**Percentages (%)**, on the other hand, are a relative unit. They define an element's size as a percentage of its parent container's size. For example, an element with a width of `50%` will always take up half the width of its parent. This makes percentages ideal for creating flexible layouts that scale gracefully on different devices, from a large desktop monitor to a small mobile phone.
Understanding the relationship between pixels and percentages helps you translate a fixed design into a fluid, responsive layout. This tool lets you quickly see what a specific pixel size corresponds to as a percentage of a given container, which is a common task when building responsive websites.
