is this pot big enough for flowering

hi i have just brought this pot for flowering in but i was just wondering if it was big enough?this is what it looks like all it says on the pot is 5cm but i don't know if its the same as a 5 gal pot any advise would be great
thanks

Looks kind of small, 5cm is no where near 5 gallons!

5cm is really small and probably smaller than your veg pot so youll need a bigger one if you think its too small then it probably is just use your best judgement or ask someone working at the store...just find a pot that is two or three times your current pot size

well its twice the size of my veg pot so i think it will be okay just wanted some info be i trance planted thanks guys
