Wolfram Alpha Bot vs UnitConversionBot
If all you need is to convert units, UnitConversionBot (@UnitConversionBot) is the quicker tool: send “100 ft to m” as a plain message and the number comes back, across length, area, volume, weight, temperature, energy and speed, and its code is open on GitHub. It is one developer's project with no support channel. Wolfram Alpha Bot (@wolframbot) needs /wolfram before every query and is an unofficial wrapper, but behind it sits the Wolfram Alpha engine, which also handles algebra, calculus and factual questions. When a conversion turns into a real problem, such as a formula or an equation, Wolfram Alpha Bot is the right choice.

Pros and cons
Wolfram Alpha Bot
- Far more capable than a plain calculator, a real computational knowledge engine
- Handles unit conversions and complex math in the same interface
