1.6 Rem to Px – Full Calculation Guide

1.6 rem equals 25.6 pixels (px).

The conversion from rem to px depends on the root font size, which is commonly 16 pixels by default. Multiplying 1.6 rem by 16 px gives the equivalent pixel size.

Conversion Formula

The conversion formula to change rem to px is:

pixels (px) = rem value × root font size (px)

Since the root font size in most browsers is 16 pixels, multiply the rem value by 16 to get the pixel equivalent. The rem unit scales relative to the root element, so 1 rem equals 16 px by default.

Example calculation for 1.6 rem:

• Identify root font size: 16 px
• Multiply rem value by root size: 1.6 × 16 = 25.6
• Result: 1.6 rem = 25.6 px

Conversion Example

• Example 1: Convert 2.5 rem to px
  • Root font size is 16 px
  • 2.5 × 16 = 40
  • Answer: 2.5 rem = 40 px
• Example 2: Convert 0.75 rem to px
  • Root font size is 16 px
  • 0.75 × 16 = 12
  • Answer: 0.75 rem = 12 px
• Example 3: Convert 3 rem to px
  • Root font size is 16 px
  • 3 × 16 = 48
  • Answer: 3 rem = 48 px
• Example 4: Convert 1.2 rem to px
  • Root font size is 16 px
  • 1.2 × 16 = 19.2
  • Answer: 1.2 rem = 19.2 px

Conversion Definitions

rem: rem stands for root em, unit in CSS that scales relative to the root element’s font size. Unlike em, rem is consistent across elements, helping maintain proportional sizing. 1 rem equals the font size of the document’s root, commonly 16 pixels, but adjustable by CSS.

px: px means pixel, a fixed unit representing a single dot on a display screen. Pixels are absolute units in CSS, unaffected by font size changes. They provide precise control over layout dimensions but lack scalability compared to relative units like rem or em.

Conversion FAQs

Can the root font size be changed, affecting rem to px conversion?

Yes, the root font size is adjustable via CSS. If it changes from 16 px to another value, the conversion from rem to px also changes, since rem units always multiply by the current root font size, not fixed 16.

Why would someone use rem instead of px for font sizes?

Using rem allows consistent scaling across a webpage when root font size changes, making designs more flexible and accessible, especially for users resizing text. Pixels are fixed and do not adapt as easily.

Does screen resolution affect rem to px conversion?

No, rem to px conversion depends on the root font size defined in CSS, not on screen resolution. However, how pixels appear visually can vary with screen density, but the numeric conversion stays the same.

What happens if the input rem value is negative?

Negative rem values convert to negative pixels by multiplying with the root font size. This can be useful for CSS properties like margins or positioning where negative offsets needed.

Is it possible for rem to px conversion to vary between browsers?

Generally, no. Browsers default root font size to 16 px, so conversion is consistent. But if user or website styles change root font size, or browser settings override defaults, conversions differ accordingly.
