0.67 Em to Px – Answer with Formula

0.67 em is equal to 10.72 pixels (px).

The conversion from em to pixels depends on the base font size of the element or document, which most browsers set to 16 pixels by default. Multiplying 0.67 by 16 gives the pixel value, which is 10.72 px in this case.

Conversion Formula

The formula to convert em units into pixels is:

pixels = em × baseFontSize

Here, the baseFontSize is the size of 1 em in pixels, which is usually 16px in many browsers, but it can be different depending on user settings or CSS.

The formula works because an em is a relative unit based on the current font size. So, multiplying the em value by the pixel value of one em gives the equivalent pixel size.

Example calculation for 0.67 em:

• Base font size = 16px
• Multiply: 0.67 × 16 = 10.72 px

Conversion Example

• Convert 1.25 em to px
  • Base font size = 16px
  • Calculation: 1.25 × 16 = 20 px
• Convert 0.5 em to px
  • Base font size = 16px
  • Calculation: 0.5 × 16 = 8 px
• Convert 2 em to px
  • Base font size = 16px
  • Calculation: 2 × 16 = 32 px
• Convert 0.33 em to px
  • Base font size = 16px
  • Calculation: 0.33 × 16 = 5.28 px

Conversion Definitions

em: A relative CSS unit representing the computed font size of the element or its parent. The value changes depending on the font size context, making it scalable. For example, 1 em equals the current font size, so 2 em is twice the size, and 0.5 em is half.

px: An absolute CSS unit representing a pixel on the screen. Pixels are fixed units that do not scale with font or element size changes. One pixel is the smallest visible dot on a digital display, widely used for precise layout control.

Conversion FAQs

Can the base font size for em to px conversion be different than 16px?

Yes, the base font size can differ depending on the CSS settings or user preferences. Many browsers set 16px as default, but if the base font size changes in CSS, the pixel value for an em changes accordingly. Always check the context where the em is used.

What happens if I use em units inside nested elements with different font sizes?

Em units are relative to the parent element’s font size, so nested elements with different font sizes cause the em value to scale relative to their immediate parent’s size. This can cause compounded scaling, making pixel values vary depending on the nesting depth.

Why does 0.67 em sometimes look different on mobile devices compared to desktop?

Mobile devices may adjust their default font sizes or zoom settings, affecting how em units convert to pixels. Variations in device pixel density and user settings cause em-based sizes like 0.67 em to appear differently across devices.

Is it better to use em or px for font sizing in web design?

Using em units allows more flexible and scalable typography, adapting to user preferences and accessibility needs. Pixels provide precise control but lack scalability. Choosing depends on design goals and the need for responsiveness.

How do I find the exact pixel value of 0.67 em if the root font size is unknown?

You can inspect the computed font size of the element or its root in the browser developer tools. Multiply 0.67 by that computed size in pixels to get the exact pixel value. Without knowing the base size, conversion is approximate.
