How to Convert EM to PC
Canonical guidance that also applies to the reverse conversion on the same page.

Step 1: Define the relevant context

Confirm the values that influence the conversion. Relative units like REM, EM, VW, VH, and % depend on the root font-size, parent font-size, parent length, or viewport dimensions.

Step 2: Convert the source value into pixels

Normalize the source unit into pixels first. This gives you a consistent base for accurate conversion across all CSS unit types.

Pixels = EM × Parent Font Size

Step 3: Convert pixels into the target unit

Once the intermediate pixel value is known, convert it into picas using the target formula below.

Result = Pixels / 16

Understanding EM

The em unit is relative to the current parent font-size, which makes it flexible for nested interface patterns and component-local scaling.

Understanding Picas

Picas are another print-focused unit. They can be useful when translating editorial or publishing measurements into web-friendly values.
