PX to REM converter
computation using the font-size of the root element below.
Comprehensive explanation of px to rem conversion.

Description
"Rem" is an abbreviation for "root em" and is a relative unit, which means that its value depends on the font size of the root element. If the font size of the root element is set, all other element sizes that use the rem unit are calculated on the basis of that root size. Scaling and adjusting font sizes without affecting individual elements is made easier by the use of rem units, which help to maintain consistent font sizes across the entire design. The root element's font size, which most browsers set to 16 pixels by default, is equal to one rem.
Px to rem can be converted by dividing the pixel value by the root font-size. For example, if an element font-size is 24px and the root element font-size is 16px then the corresponding rem value of the element is equal to (24 / 16) = 1.5rem. Converting pixels to rem is made easier with our tool, which allows you to do it as often as you'd like.
