50 px equals approximately 3.125 mobile units.
The conversion from pixels (px) to mobile units depends on the standard screen width assumed for mobile devices. By dividing the pixel value by the base width, the equivalent mobile measurement is calculated, allowing scaling across different device sizes.

Conversion Formula
The formula to convert px to mobile is: mobile = px ÷ 16. This is based on an assumed typical mobile screen width of 320px, divided into 20 units, making each unit equivalent to 16px. Dividing the pixel value by 16 gives a relative unit that scales better on mobile screens.
Why it works: Mobile interfaces use relative units to adapt content size to various screen sizes. Pixels are absolute, so converting them helps maintain consistency across devices.
Example:
- Given 50 px, divide by 16: 50 ÷ 16 = 3.125 mobile
- This means 50 pixels is about 3.125 units in mobile measurement
Conversion Example
- Convert 32 px to mobile:
- Divide 32 by 16
- 32 ÷ 16 = 2 mobile
- Convert 64 px to mobile:
- Divide 64 by 16
- 64 ÷ 16 = 4 mobile
- Convert 100 px to mobile:
- Divide 100 by 16
- 100 ÷ 16 = 6.25 mobile
- Convert 20 px to mobile:
- Divide 20 by 16
- 20 ÷ 16 = 1.25 mobile

Conversion Definitions
px (pixel): A pixel is the smallest controllable element of a digital image or display, representing a single point in a raster graphics. Pixels are absolute units that measure digital content but do not scale automatically across different screen sizes or resolutions.
mobile (unit): Mobile units represent a relative measurement system designed to scale content sizes appropriately for mobile device screens. Unlike pixels, these units adapt to different screen widths, improving consistency and readability on smaller displays.
Conversion FAQs
Why divide pixels by 16 to get mobile units?
Dividing by 16 comes from the base design assumption where 1 mobile unit equals 16 pixels. This base is used because many design systems use 320px wide screens divided into 20 units (320 ÷ 20 = 16), so dividing px by 16 converts absolute pixels into relative mobile units that adjust better on devices.
Can the px to mobile conversion change with different devices?
Yes, the conversion can vary if the assumed base screen width or unit size changes. The 16px per mobile unit is a common standard, but some projects may use different bases depending on their target devices or design requirements, affecting the conversion result.
What happens if I use decimals in mobile units?
Decimals in mobile units are normal and expected, since pixels don’t always divide evenly. Most modern CSS and design frameworks support fractional units, allowing smoother scaling and better visual consistency across different screen resolutions.
Is this conversion accurate for all mobile devices?
This conversion provides a good approximation but may not be perfectly accurate for all devices. Different phones and tablets have various pixel densities and screen sizes, so relative units help adapt designs, but pixel-perfect conversion depends on device specifics.
How to apply this conversion in CSS?
You can convert pixel values to mobile units by dividing pixel numbers by 16, then use those values in CSS properties such as width, height, font-size, etc., using relative units like rem or em, which behave similarly to mobile units for responsive designs.
