A Walkthrough of CSS Length Units You Can Use for Font Size
By Asha Laxmi

CSS provides a lot of units for developers to specify the length of different properties like margin, padding, line-height or font-size. The reason we have many units is that they are designed to serve different purposes. Even though you can use these units to specify the same value for a given CSS property, the actual magnitude of that value is calculated differently. This can make some units useful for situations where other units might not do that well.
