How to derive textsize from a character's width and font

Say I want to draw the string "5" to the screen. I've created a Paint object for this with the default android font.

I know how to measure text like this: mTextPaint.measureText(...params...) to get the width of the text in float format.

But now I want to do this backwards. I have calculated the maximum width (float) that the character ('5') may use.

How do I find the right textSize using: the string or character ("5"), the Paint object for drawing the text and the maximum width I want to allow the character to take up?

String text = "5";
float fitw = 100.0f;
mTextPaint.setTextSize(fitw * (mTextPaint.getTextSize() / mTextPaint.measureText(text)));
