A ballpark figure, also called a ballpark estimate, is an approximate number used to describe a quantity, usually based on an informed guess or rough calculation. It’s usually used in situations where an exact number is not known, is difficult to determine, or is simply not important to the purpose of the conversation.

Here are some examples of ballpark figures:

• The number of people who attended the game: “There were around 40,000 people at the game.”
• The amount of money spent on tickets: “The tickets cost around $200 each.”
• The distance to the park: “The park is about 20 miles from here.”

Key points:

• Ballpark figures are estimates, not exact numbers.
• They are based on a reasonable guess or rough calculation.
• They are used when an exact number is not known, difficult to determine, or simply not important.
• The term “ballpark figure” is typically used in a humorous way.
