Generally speaking, meetings and conferences are all events where people get together to consider a particular subject; usually the difference is one of scale. Meetings can be more informal, usually involve just a few people and can often be held within a company. Conferences on the other hand, can be held in company meeting rooms, but more often than not, are held externally as they can involve larger numbers of attendees and people from different businesses. Hotels and Conference & Training centres are often better placed to offer the facilities, equipment and environment required for a successful event.

A confrence is with A LOT of people. Like, many people from all over the country meet in one city to discuss things. It is like a giant meeting. Examples: I will go to Chicago for a 4 day confrence. I have a meeting this afternoon with my boss.

a meeting may be between any number of people beginning at two. A conference is likely many people, not a few.
