什么是\f@size？

为啥不起作用\convertto{\f@size bp}{pt}？

根据此答案的评论，Microsoft Word 使用大点来测量字体：https://tex.stackexchange.com/a/274609/13552

我开始以我能想到的最合乎逻辑的方式将点转换为大点，将\convertto{bp}{1pt}1pt 转换为 bp。

\show将停止 tex（就像出现错误消息一样）并显示任何命令的含义。

\makeatletter
\show\f@size

生产

*\show\f@size
> \f@size=macro:
->10.

\f@size是当前标称字体大小，以pt（不是bp）为单位。

发布的代码产生错误

! Undefined control sequence.
\thefontsizePoint ...ent font size is: \convertto

并且您没有表明其预期行为，因此很难对此发表评论。

由于您正在使用 expl3，因此您可以使用其函数在单位之间进行转换，例如

\dim_to_decimal_in_unit:nn { 1bp } { 1mm }

将显示 1bp 单位为 mm
