600 Pixels to Rem – Full Calculation Guide

600 pixels is equal to 37.5 rem.

The conversion from pixels to rem depends on the root font size, which is usually 16 pixels in most browsers. By dividing 600 pixels by 16, you get the equivalent size in rem units, which scale relative to the root font size.

Conversion Formula

The formula to convert pixels to rem is:

rem = pixels ÷ root font size

This works because rem units are relative to the root element’s font size, which is set in pixels. The default root font size in browsers is 16 pixels unless changed by CSS. So dividing the pixel value by 16 converts it to rem.

Example:

Convert 600 pixels to rem:

• Root font size = 16 pixels
• Divide 600 by 16: 600 ÷ 16 = 37.5
• So, 600 pixels = 37.5 rem

Conversion Example

• Convert 320 pixels to rem:
  • Root font size = 16 pixels
  • 320 ÷ 16 = 20
  • Result: 320 pixels = 20 rem
• Convert 48 pixels to rem:
  • 48 ÷ 16 = 3
  • Result: 48 pixels = 3 rem
• Convert 150 pixels to rem:
  • 150 ÷ 16 = 9.375
  • Result: 150 pixels = 9.375 rem
• Convert 75 pixels to rem:
  • 75 ÷ 16 = 4.6875
  • Result: 75 pixels = 4.6875 rem

Conversion Definitions

Pixels: Pixels are the smallest units of a digital image or display, representing a single point of color on a screen. They form the basis of screen resolution and layout measurements in digital design. Pixel sizes are absolute and fixed in relation to screen density.

Rem: Rem stands for “root em” and is a relative CSS unit that scales according to the root element’s font size. Unlike pixels, rem units allow flexible and scalable layouts, adapting to user settings or device preferences by multiplying the root font size by the rem value.

Conversion FAQs

Does the root font size change the pixel to rem conversion?

Yes, the root font size directly affects the conversion. The calculation divides pixels by the root font size, so if the root font is set to 20 pixels instead of 16, 600 pixels would convert to 30 rem instead of 37.5 rem. Always check the root font size before converting.

Can I rely on rem units for all screen sizes?

Rem units adapt to the root font size, which can be changed for different devices via CSS media queries or user settings. This makes rem useful for scalable designs. However, if the root font size is not consistent, rem values might vary between devices unless carefully controlled.

Why use rem over pixels in web design?

Rem units provide scalability and accessibility, letting text and layouts resize based on user preferences or device settings. Pixels are fixed, which can cause issues on high-resolution or zoomed screens. Rem allows responsive designs that adjust more gracefully to different environments.

What happens if I change the browser’s default font size?

Changing the browser’s default font size alters the root font size, affecting rem calculations. For example, if the default is changed from 16 to 18 pixels, 600 pixels will convert to 33.33 rem instead of 37.5 rem. This can impact how layouts and text scale across different users.

Is rem unit always based on 16 pixels root font size?

No, 16 pixels is the default root font size in most browsers but it can be overridden by CSS. If a website sets the root font size to another value, rem units will scale relative to that new size. Therefore, rem values depend on the root font size, not a fixed 16 pixels.
