Converter Bot
Converter Bot leans on menus instead of memorized syntax. Send /start and it walks you through /categories to pick a measurement type, /units to see the exact codes it accepts inside that category, and /examples if you want to see a sample query before typing your own. It is built by Onix-Systems, a software development studio, rather than an anonymous side project, which shows in how deliberately the command set is laid out.
The standout feature for a Russian-speaking audience is that the interface genuinely ships in both English and Russian — most converter bots online only bother with English. That makes it one of the few options in this category where you are not guessing at unit abbreviations in a foreign language.
It trades a little speed for that structure: there is no inline mode, so you need to open a chat with the bot rather than firing off a query from wherever you are typing. There is also no visible monthly-user count on its public profile, so it is hard to say how many people actually rely on it day to day — but the documented commands and the identifiable company behind it are reassuring signs for a niche utility bot.
