@GaurangTandon Why did you remove mathrm ?

told you before

@GaurangTandon Why are units necessary?

@AvnishKabaj well why do you want to use \mathrm on pure numbers? I fail to see the reason, mind explaining?

@GaurangTandon it looks straight and roman

@AvnishKabaj aren't all numbers already straight within the two $s?

@GaurangTandon not on my phone at least

Anyway there is a reason

\text{} makes it automatically roman

That's why

@AvnishKabaj No. It requests that symbols will be set in roman (upright) type, which might be correct, but it might be wrong, i.e. like here. Here it has no effect at all, as \text is always set in roman type. If you want to know more, please have a look here and here. – Martin - マーチン♦ 6 mins ago

@AvnishKabaj martin actually removed those \mathrms you inserted...

@AvnishKabaj where does it tell you to enclose unitless fractions in \mathrm?

Yeah I know

I'm not saying that you should enclose bare text

then what are you saying?

Nothing

:-O
