I want the size of the text to be in .dp so that it doesn't change according to the system font. How to achieve this in Jetpack Compose "Text" composable

The Compose team does not intend to provide that possibility, em are a bit pita to use, but there is an easy workaround should anyone really need it.

@Composable
fun dpToSp(dp: Dp) = with(LocalDensity.current) { dp.toSp() }

Text("ABCD", fontSize = dpToSp(15.dp))

You can use extension properties：

private fun Int.textDp(density: Density): TextUnit = with(density) {
    this@textDp.dp.toSp()
}


val Int.textDp: TextUnit
    @Composable get() =  this.textDp(density = LocalDensity.current)
