Pixel to Percentage Converter

Convert pixel to percentage using the formula:
Percentage = (Pixel / Base Width) × 100

Pixel

Base Width (px)

Understanding Pixel to Percentage Conversion

In CSS, pixels (px) are an absolute unit, while percentages (%) are relative units that depend on the parent container's width. When converting pixels to percentages, we express the pixel value as a proportion of a base width (typically the width of the parent container).

Steps to Convert Pixels to Percentage

Step 1: Determine the Base Width
The base width is the width of the parent container (e.g., a <div> or <body> tag). For example, if a container has a width of 500px, then all percentage values will be calculated based on 500px.
Step 2: Use the Conversion Formula
The formula to convert pixels to percentage is:
```
Percentage = (Pixel Value / Base Width) × 100
```
Step 3: Apply in CSS
Use the calculated percentage value in CSS styles for elements like width, height, margin, padding, etc.

Examples of Pixel to Percentage Conversion

Example 1: Converting 50px to Percentage

Assume the parent container width is 500px. Using the formula:

(50 / 500) × 100 = 10%

So, 50px is equivalent to 10% of a 500px container.

Example 2: Converting 100px to Percentage

If the parent container width is 800px:

(100 / 800) × 100 = 12.5%

100px is 12.5% of 800px.

What is the Base Width?

The base width is the reference width from which percentage values are calculated. It is usually the width of the parent container.

.container {
  width: 600px; /* Base Width */
}

.child {
  width: 50%; /* 50% of 600px = 300px */
}

What are Percentages in CSS?

Percentages are relative values in CSS. They depend on the size of their parent element rather than being fixed like pixels.

Common Uses of Percentage in CSS

Width & Height:

.box {
  width: 80%; /* 80% of parent width */
  height: 50%; /* 50% of parent height */
}

Font Size (Relative to Parent Element):

.text {
  font-size: 120%; /* 120% of parent font size */
}

Margins & Padding (Relative to Parent Width):

.content {
  margin-left: 10%; /* 10% of parent width */
}
