60 pt equals 3.75 em when converted assuming the standard reference where 1 em equals 16 pixels and 1 pt equals 1.333 pixels.
The conversion from points (pt) to em units depends on the relationship between points, pixels, and ems. Since 1 pt equals 1.333 pixels and 1 em equals 16 pixels by default, converting 60 pt to em requires converting points to pixels first, then pixels to em. This way, the size remains consistent across CSS units.

Conversion Formula
The formula converts points (pt) to em by first changing points into pixels, then pixels into em units. Since 1 pt = 1.333 pixels, multiply the pt value by 1.333 to get pixels. Then, because 1 em equals 16 pixels in default browser settings, divide the pixels by 16.
Formula:
em = (pt × 1.333) ÷ 16
Why this works: Points are a print unit, pixels are screen units, and em is a relative unit in CSS based on font size (usually 16px). This two-step conversion keeps sizes consistent.
Example for 60 pt:
60 pt × 1.333 = 79.98 pixels
79.98 pixels ÷ 16 = 4.999 em (rounded 5.000 em)
Conversion Example
- 45 pt:
- Multiply 45 pt by 1.333 = 59.985 pixels
- Divide 59.985 pixels by 16 = 3.749 em
- Result: 45 pt = 3.749 em
- 30 pt:
- 30 × 1.333 = 39.99 pixels
- 39.99 ÷ 16 = 2.499 em
- Result: 30 pt = 2.499 em
- 75 pt:
- 75 × 1.333 = 99.975 pixels
- 99.975 ÷ 16 = 6.249 em
- Result: 75 pt = 6.249 em
- 50 pt:
- 50 × 1.333 = 66.65 pixels
- 66.65 ÷ 16 = 4.166 em
- Result: 50 pt = 4.166 em

Conversion Definitions
pt: A point (pt) is a physical unit of measurement traditionally used in print, where 1 pt equals 1/72 of an inch. In digital design, points map to pixels depending on screen resolution, with 1 pt usually equal to about 1.333 pixels, used to size fonts and layout elements.
em: An em is a relative CSS unit based on the font size of the parent element. It scales proportionally, so 1 em equals the current font size in pixels. If the font size is 16px, then 1 em equals 16 pixels, making it flexible for responsive design and scaling text.
Conversion FAQs
Does the default browser font size affect pt to em conversion?
Yes, em units are relative to the current font size, which is often 16 pixels by default in browsers. Since the pt to em conversion uses pixels as a middle step, changing the base font size will change the em value for the same pt value.
Why multiply by 1.333 when converting pt to pixels?
The point is defined as 1/72 of an inch, and pixels per inch (ppi) commonly assumed for screens is 96 ppi. So, 96 pixels ÷ 72 points = 1.333 pixels per point. Multiplying points by 1.333 converts them into pixels.
Can pt units be used directly in CSS instead of em?
Pt units can be used in CSS but are absolute and don’t scale well on different screen sizes or user settings. Em units scale relative to the font size, making them better for responsive layouts and accessibility.
Is the 16-pixel base for em always fixed?
No, the base font size can be changed in CSS or by user settings in browsers. The em unit always refers to the current element’s font size, so it might not be exactly 16 pixels if the base size is altered.
What happens if I use pt in mixed units with em in CSS?
Using mixed units like pt and em in CSS can cause inconsistent sizing, especially if the base font size changes. Pt remains absolute, while em scales relative, so mixing them may cause layout or readability issues.
