Describe the query

Can anyone tell px:fp ratio or code to convert fp to px. I am building a HarmonyOS application and I want to set the width of a component to 20fp and setWidth​(int width) takes width in px.

Button button = new Button(getContext());
button.setWidth(width);

Create the query with harmonyos tag in stackoverflow and share the link here:

Answered by Shirley HarmonyOS provides the AttrHelper tool class to implement conversion between fp and px.

AttrHelper.fp2px()
