60 pt equals 3.75 em when converted assuming the base font size is 16 pixels.
Table of Contents
The conversion from points (pt) to em depends on the base font size, which is commonly 16 pixels in browsers. Since 1 pt equals 1.333 pixels, and 1 em equals the base font size in pixels, you can calculate em by dividing the pixel value of pt by the base font size.

Conversion Formula
The formula to convert points (pt) to em units involves converting points to pixels first, then dividing by the base font size in pixels.
One point is defined as 1/72 of an inch, and 1 pixel is about 1/96 of an inch, so 1 pt equals 1.333 pixels (96/72 = 1.333). Since 1 em is equal to the base font size in pixels, which is often 16 pixels, the conversion becomes:
em = (pt × 1.3333) ÷ base font size
For example, converting 60 pt to em:
- Multiply 60 pt by 1.3333 to get pixels: 60 × 1.3333 = 80 pixels
- Divide pixels by base font size: 80 ÷ 16 = 5 em
But since browsers might vary, if base font size is 16px, 60 pt equals 5 em. If base font size differs, em value changes.
Conversion Example
- Convert 40 pt to em:
- 40 pt × 1.3333 = 53.332 pixels
- 53.332 ÷ 16 (base font size) = 3.333 em
- Convert 50 pt to em:
- 50 pt × 1.3333 = 66.665 pixels
- 66.665 ÷ 16 = 4.166 em
- Convert 70 pt to em:
- 70 pt × 1.3333 = 93.331 pixels
- 93.331 ÷ 16 = 5.833 em
- Convert 80 pt to em:
- 80 pt × 1.3333 = 106.664 pixels
- 106.664 ÷ 16 = 6.666 em

Conversion Definitions
pt (point): A typographic unit of measure used in print and digital media, defined as 1/72 of an inch. In digital design, points translate to pixels based on screen resolution, where usually 1 pt equals 1.333 pixels. Points are often used to specify font sizes and spacing.
em: A relative unit in CSS representing the current font size of the element. 1 em equals the computed font size of the parent or the element itself. It allows flexible scaling of text and layout elements depending on user settings or inherited font size.
Conversion FAQs
Does the base font size affect the pt to em conversion?
Yes, it does. Since em units are relative to the base font size, changing that base size directly alters the em value equivalent to a fixed pt measurement. A different base font size means the same pt value converts to a different em value.
Why is 1 pt equal to 1.333 pixels?
This comes from the ratio between points and pixels based on screen DPI settings. Points are fixed at 1/72 inch, while pixels depend on screen resolution usually 96 DPI. So 96/72 results in 1.333 pixels per point, making pt a device-independent unit.
Can I use em units instead of points for font sizes in CSS?
Yes, em units are often preferred in web design because they scale with the font size context, allowing flexible and accessible layouts. Points are absolute units mostly from print design, less flexible on different screen sizes.
What happens if I use a different base font size than 16px?
The em conversion changes accordingly. For example, if the base font size is 20px, 60 pt converts to (60 × 1.3333) ÷ 20 = 4 em instead of 5 em. Always check the base font size when converting.
Is the conversion formula the same for all browsers?
Mostly yes, because browsers follow CSS standards for unit definitions. However, rendering differences and user settings can cause slight variation in the actual size on screen, but the math behind conversion stays consistent.
