24 pt equals 1.5 rem.
The conversion from points (pt) to rem is based on the fact that 1pt is equal to 1/72 inch and the browser default font size is 16 pixels, which is 1 rem. Using the pixel equivalent of points, 24 pt converts to 1.5 rem by dividing the pixel value by 16.

Conversion Formula
The formula to convert point (pt) to rem is based on pixels as an intermediary unit. One point equals 1/72 of an inch, and the CSS pixel density standard is 96 pixels per inch. So, 1 pt = 96/72 px, which is 1.3333 px.
Since rem is relative to the root font size, and default root font size is 16 px, rem value is calculated by dividing pixels by 16.
Formula:
rem = (pt × 96 / 72) / 16
Step-by-step for 24 pt:
– Convert pt to pixels: 24 × 96 / 72 = 32 px
– Convert px to rem: 32 ÷ 16 = 2 rem
Conversion Example
- Convert 12 pt to rem:
- 12 × 96 / 72 = 16 px
- 16 ÷ 16 = 1 rem
- Convert 18 pt to rem:
- 18 × 96 / 72 = 24 px
- 24 ÷ 16 = 1.5 rem
- Convert 36 pt to rem:
- 36 × 96 / 72 = 48 px
- 48 ÷ 16 = 3 rem
- Convert 6 pt to rem:
- 6 × 96 / 72 = 8 px
- 8 ÷ 16 = 0.5 rem
- Convert 48 pt to rem:
- 48 × 96 / 72 = 64 px
- 64 ÷ 16 = 4 rem

Conversion Definitions
pt (point): A typographic unit of measure, where 1 point equals 1/72 of an inch. Points are used to define font sizes and other print measurements. In digital screens, points convert to pixels based on screen resolution and pixel density.
rem (root em): A CSS unit relative to the root element’s font size. Unlike em, rem always references the root font size, usually 16 pixels, allowing for consistent scaling of elements across a webpage regardless of nesting.
Conversion FAQs
Why does converting 24 pt to rem sometimes give different results?
Because rem depends on the root font size, if the root font size is not the default 16px, the conversion changes. For example, if the root font is 20px, the rem value for 24 pt would be different. Points convert to pixels first, then pixels divided by the root font size gives rem.
Can negative point values be converted to rem?
Technically yes, negative pt values convert mathematically to negative rem, but negative font sizes don’t make sense in CSS, so negative values are not practical for styling text.
Is the conversion formula the same for all devices?
The formula assumes standard screen resolution (96 dpi) and root font size (16px). Different devices with varied resolutions or user settings can affect actual rendering, but the formula stays consistent for CSS calculations.
How accurate is the pt to rem conversion?
The conversion is precise mathematically, but actual display can vary slightly due to browser rendering, zoom level, or device pixel density. It’s good for design consistency but may not be pixel-perfect on all environments.
Why use rem instead of pt in web design?
Rem allows scalability and responsiveness, adapting to user preferences and device settings. Pt is fixed and better for print, but rem units create flexible layouts in web design that improve accessibility and readability.
