1.4 Rem to Px – Full Calculation Guide

1.4 rem equals 22.4 pixels (px) when the root font size is 16px.

This conversion is based on the fact that 1 rem unit equals the root element font size in pixels. Since the default root font size is 16px in most browsers, multiplying 1.4 by 16 gives the pixel value.

Conversion Formula

The formula to convert rem to px is:

pixels (px) = rem value × root font size (px)

Since rem measures relative to the root font size, which is most often 16px by default, multiplying rem number by 16 yields the pixel equivalent. This works because rem units scale based on the root element, so if the root size changes, pixel equivalent changes too.

Example calculation for 1.4 rem:

• 1 rem = 16 px
• 1.4 rem = 1.4 × 16 px
• 1.4 rem = 22.4 px

Conversion Example

• Convert 2.5 rem to px:
  • Multiply 2.5 by 16 (root font size)
  • 2.5 × 16 = 40 px
  • So, 2.5 rem equals 40 px
• Convert 0.75 rem to px:
  • 0.75 × 16 = 12 px
  • Thus, 0.75 rem equals 12 px
• Convert 3 rem to px:
  • 3 × 16 = 48 px
  • Meaning 3 rem equals 48 px
• Convert 1 rem to px:
  • 1 × 16 = 16 px
  • So, 1 rem equals 16 px
• Convert 0.5 rem to px:
  • 0.5 × 16 = 8 px
  • Therefore, 0.5 rem equals 8 px

Conversion Chart

The following table shows rem values from -23.6 to 26.4 and their pixel equivalents using the 16px root font size. You can read the rem value in the first column and find the corresponding px value in the second. Negative rem values indicate sizes smaller than zero, which might be used for offsets or transformations in styling.

Conversion Definitions

rem: A CSS unit that stands for “root em,” represents font size relative to the root element’s font size. Unlike em, rem always base on the root, not the parent. This makes rem useful for scalable and consistent sizing across a webpage.

px: Pixel, a fixed unit representing a single dot on the screen. It’s absolute, meaning 1px always equal the same size regardless of font settings or zoom. Pixels are used for precise control over layout and visuals.

Conversion FAQs

Can root font size change affect rem to px conversion?

Yes, if the root font size is modified in CSS, rem values scale accordingly. For example, if root font size is set to 20px instead of 16px, then 1.4 rem equals 28 px instead of 22.4 px. This dynamic scaling allows flexible design but requires attention when converting.

Why might 1.4 rem not equal 22.4 px in some cases?

This can happen if the browser’s default root font size differs, or user settings override it. Also, if the root element’s font size was changed via CSS, the pixel equivalent will change. Always check the root font size before assuming rem to px conversions.

Is rem better than px for responsive designs?

Rem units scale with root font size, which can be adjusted for different devices or user preferences. This makes rem more flexible than px, which is fixed. Using rem helps create layouts that adapt more easily to various screen sizes and resolutions.

Can rem values be negative?

Technically, rem values can be negative, which translates to negative pixel values. This might be used in CSS for positioning or offsetting elements. However, negative sizes for font or box dimensions usually cause layout issues or no visible output.

How precise is the conversion from rem to px?

The conversion is exact as long root font size is known and constant. Multiplying rem by the root font size gives exact pixel values. Using fixed root sizes ensures consistent results across browsers and devices, but scaling or zoom can affect perceived sizes.
