(Official NBA weight is 22 ounces (avoirdupois) = 623.7 grams.)

High School basketballs may be lighter: 20 ounces -

According to Rule 1 Section 12 Article 1e. parts 1 and 2, "The weight shall be within a minimum of 20 ounces to a maximum of 22 ounces for high school boys competition and within a minimum of 18 ounces to a maximum of 20 ounces for high school girls competition."

Basketballs actually come in four sizes

  • Size 3: circumference 22 to 22.5 inches, weight 10-11 ounces, recommended for small children (age 5-8). It has a diameter of 7 to 7.16 inches and a radius of 3.5 to 3.58 inches

  • Size 6: circumference 28.5 to 29 inches, weight 20 ounces, recommended for boys and 12-14 and girls and women age 12 and up. This is the official game ball for women's high school, university and professional basketball. It has a diameter of 9.07 to 9.23 inches and a radius of 4.54 to 4.62 inches.
  • Size 7: circumference 29.5 to 30 inches, weight 22 ounces, recommended for men and boys age 15 and up. This is the official game ball for men's high school, university and professional basketball. It has a diameter of 9.39 to 9.55 inches and a radius of 4.7 to 4.77 inches.

Since "air" does not weigh anything, the overall weight then of the basketball would be the same if inflated or deflated.
