Not really, or it has some pretty weird ideas about preferred units in my region. When trying to get a conversion for 1 cup, it tells me it's 0.5 pints. My region is Finland, language is Finnish, and roughly no-one understands those units.
The metric conversions are idiotic. Converting "1 cup" to 5 decimal places is misleading, and offering alternatives in l / cl / ml (with a capital ell??) is useless. The addition of cm^3 is the cherry on top :)
This was clearly designed by someone who has never used the metric system.
A human would convert it to "1/4 liter" or "250ml".
Edit: Actually, a human would convert "1 cup of flour" into "150g flour", since most local recipes use weight instead of volume for solids. Which shows that good localisation is a lot more than just literal translation + unit conversion.
