(Used for 'rem' conversions)
(Used for 'em' conversions)
Enter a value in any field, and the others will update automatically based on the context font sizes provided above.
How to Use
- Set the "Root Font Size" (usually 16px) for accurate `rem` conversions.
- Set the "Parent Font Size" for the context where `em` units will be used.
- Enter a value into any of the unit fields (px, em, rem, pt).
- The other fields will automatically update with the converted values.
Conversion Notes:
- `1em` = Parent Font Size (in px)
- `1rem` = Root Font Size (in px)
- `1pt` = 1/72 inch ≈ 1.333 px (standard CSS conversion)
Why Convert CSS Units?
- Responsive Design: Understand how relative units (em, rem) translate to pixels at different base sizes.
- Accessibility: Using relative units like `rem` can improve accessibility for users who change their browser's base font size.
- Typography: Convert between points (common in print) and pixels (common on web).
- Development Workflow: Quickly convert values when working with different unit requirements.
