But they don’t need to. I will show you an easy way to convert pixels into em. Before start, you need to understand the full concept. SO, don’t skip anything

# Base Pixel:

By default, browser font size is 16 px and we know that 16px =1em. Now do some school math.

I called these values(16px,32px,48px,64px) base pixels. We will calculate other values with respect to these base pixels.

**Tip-1:** Memorise these base pixels. Remember that for an increase of 16px, em is an increased by 1

# 4 Increment:

But what about values like 20px, 36px, 60px? They all are 4px away from their respective base pixel. Let’s do another math:

**So for every 4px em value increases by 0.25em. Such as:**

**Tip-2: **For every increase of 4px from the base pixel, em is increased by 0.25

# 8 increment:

Suppose we have 40 pixels, it is 8 px away from its base pixel 32.

**Tip-3:** For every increase of 8 px from the base pixel, em in increase by 0.5

# Summary:

Using these laws, we cal do almost 90% of the task of responsive web design. Let’s recap :**Tip-1:** Memorise these base pixels. Remember that for an increase of 16px, em is an increased by 1

**Tip-2: **For every increase of 4px from the base pixel, em is increased by 0.25

**Tip-3:** For every increase of 8 px from the base pixel, em in increase by 0.5

**Tip-4:** For every increase of 32 px from the base pixel, em is increased by 2

**Tip-5:** For every increase of 160 px from the base pixel, em is increased by 10

# Conclusion:

IF use understands these 5 tips, you will no longer need to use the pixel to em calculator anymore. I hope this article is helpful to you. Follow me for more articles.
