I am using LaTeX template for a thesis in English. Now I need to write my thesis in Russian using the same template. I added:

\documentclass[11pt, a4paper, oneside]{Thesis}


Everythig works perfectly apart from units. For example I want to write units in Russian 25 ${м^3 с^{-1}}$ but I have 25 3-1. What else I need to add or remove in the index I added? Or where is my mistake?

By default there's no non-latin symbols in math mode. Use 25$\,\text{м}^3\text{с}^{-1}$ or 25\,м$^3$с$^{-1}$. – Eddy_Em Jan 23 '13 at 7:00
@Eddy_Em I'm pretty sure that comment should really be an answer. – Michael Kjörling Jan 23 '13 at 9:13
@Eddy_Em Thank you! Both lines work perfectly. Didn't know about this way of coding. – Sasha Jan 23 '13 at 11:43
@Michael Kjörling, its length too small for real answer. – Eddy_Em Jan 23 '13 at 16:53

Default behaviour of math mode in latex don't allow to use non-ASCII symbols.

To use russian letters in math mode you can include them into macro \text{}:


or put them outside:


Another variant is to use package mathtext:


Option warn will show warnings on every cyrillic letter in formulae (that's useful for avoiding misprints).
