Em to Pixels Converter
Convert CSS em units to pixels based on the parent element font size.
Pixels
24.0 px
Formula
## Em to Pixels **Pixels = Em x Base Font Size** ### What is an Em? In CSS, 1em equals the computed font size of the parent element. If the parent is 16px, then 1em = 16px, 1.5em = 24px, 0.875em = 14px. ### Em vs Rem - **em** is relative to the parent element font size (cascading) - **rem** is relative to the root element font size (consistent) Default browser root font size is 16px.
Exemplo Resolvido
1.5em with a 16px base font.
- 01Pixels = 1.5 x 16 = 24px
- 02Rem = 24 / 16 = 1.5rem
- 03Points = 24 x 0.75 = 18pt
Perguntas Frequentes
Why use em instead of pixels?
Em units are relative and scale with the user font size preference. This makes designs more accessible and responsive. Pixel values are absolute and do not adapt.
Should I use em or rem?
Use rem for most sizing (consistent, based on root). Use em when you specifically want sizing to cascade relative to the parent, such as padding that scales with the component text size.
