Modern responsive web design mixes CSS units: pixels (px) are fixed, while rem and em scale with font size (1 rem = 16px by default). Converting between px, rem, em and points keeps typography and spacing consistent and accessible across devices.
Front-end developers use this to translate a designer's pixel values into scalable rem/em. Enter any value to see the equivalents, assuming the standard 16px root font size.
Quick reference — 1 Pixels (px) is equal to:
| Root em | rem | 0.0625 |
| Em | em | 0.0625 |
| Points | pt | 0.750000019 |
