Conversion Formula

The formula for converting rem to px is:

px = rem × base font size

Because 1 rem equals the root element’s font size, usually 16 px in browsers, multiply the rem value by 16. This calculation changes rem units into pixel units, which are absolute measurements.

Example:

  • Given rem = 3.4375
  • Base font size = 16 px
  • Calculation: 3.4375 × 16 = 55
  • Result: 3.4375 rem equals 55 px

Conversion Example

  • Convert 2.25 rem to px:
    • Multiply 2.25 by 16
    • 2.25 × 16 = 36
    • So, 2.25 rem = 36 px
  • Convert 1.5 rem to px:
    • 1.5 × 16 = 24
    • Hence, 1.5 rem equals 24 px
  • Convert 0.75 rem to px:
    • 0.75 × 16 = 12
    • Therefore, 0.75 rem = 12 px
  • Convert 4 rem to px:
    • 4 × 16 = 64
    • Thus, 4 rem equals 64 px

Conversion Definitions

rem: Rem stands for “root em” and is a relative unit in CSS representing the font size of the root element. Unlike em units tied to parent elements, rem stays consistent across a page, enabling scalable and predictable typography and layout adjustments.

px: Px means pixels, a fixed unit of measurement in digital screens. Pixels represent individual points of display on a screen, making px an absolute length unit that controls exact sizes of elements regardless of user settings or device resolution.

Conversion FAQs

What if the base font size is not 16px, how to convert 3.4375 rem then?

If the root font size changes, the rem to px conversion must use that new value. For example, if the base font size is 18px, multiply 3.4375 by 18, which gives 61.875 px. The conversion depends on the browser or CSS settings for the root font size.

Can rem units affect responsive design when converting to pixels?

Rem units provide scalability because they depend on the root font size, which can be adjusted for device or viewport size. Converting rem to px helps understand exact sizes, but rem allows flexible scaling, which helps responsive design better than fixed px values.

Is 3.4375 rem always the same pixel size on all browsers?

Usually, browsers use 16px as default for the root font size, so 3.4375 rem equals 55 px. But this value can differ if user or developer changes browser default font size, causing the pixel equivalent to vary accordingly.

Why use rem units instead of pixels in web design?

Rem units enable flexible, scalable layouts and typography by basing sizes off the root font size. This makes it easier to adjust overall design size with a single change, unlike px units which are fixed and less adaptable to user preferences or device sizes.
