What is the standard measurements of the World Cup soccer drops?

Circumference weight 440 grams.

The diameter was not found, so let's count it s=2 pie r

Wouldn't it be better to measure it yourself?

Sphere circumferential test: FIFA approved passing criteria:

jabulani": - cm) Durability Round Sphere Test: FIFA Approved Qualification Criteria:

The maximum difference does not exceed. "jabulani": the maximum difference does not exceed the water absorption test:

FIFA approved eligibility criteria: increase in the weight of the ball by no more than 10%. “jabulani”：

Ball weight 0 increase Weight test: FIFA approved qualifying criteria: The weight of the ball is between 420 445 grams.

Jabulani': Weight 440 g (+ - 2 g) Sphere shape and size retention ability test: FIFA approved passing criteria:

2,000 hits at 50 km/h "Jabulani": 3,500 hits at 50 km/h **Performance test: FIFA approved passing criteria:

No more than 10 cm. Ball pressure test: FIFA approved passing criteria:

The ball pressure drops by no more than 20%. "Jabulani": the ball pressure drops by no more than 10%.

Attached: Football Standards:

The circumference of the sphere shall not exceed 70 cm (28 inches) and shall not be less than 68 cm (27 inches). The weight of the ball, at the start of the game, must not exceed 450 grams (16 ounces) and must not be less than 410 grams (14 ounces). The air pressure of the ball, at sea level, is to atmospheric pressure (600 grams to 1100 grams per square centimeter to pounds per square inch).

"Celebration of the whole world" specifications.

The following is a comparison of the specifications and FIFA standards of "Celebration of the Whole World".

Circumference: "Celebrity": - Centimeters FIFA standard: Centimeter roundness: The diameter of the football is measured in 16 different places.

"Celebration of the whole world": maximum error FIFA standard: maximum error water absorption: the football needs to be pressed 250 times in water.

"Celebration of Heaven": Zero weight gain FIFA Standard: Maximum weight gain of 10% Weight "Celebration of Potevio": 440 + - grams FIFA Standard: 420-445 grams.

**Performance: In the test, the ball was dropped from a height of two meters to the steel plate, which was repeated 10 times.

The height of the :* is between 143 and 149 cmFIFA standard: the difference between the highest and lowest ** height in 10 times is not more than 10 cm Pressure loss: The air pressure is measured after 3 days of inflation.

"Putian Tongqing": 10% maximum pressure loss FIFA standard: 20% maximum pressure loss"Putian Tongqing" is not made of 32 balls sewn by hand, but is made of 8 balls thermally bonded, which has higher roundness and stronger water resistance.

The World Cup schedule is divided into two stages: the qualifying stage and the final stageThe World Cup qualifying stage is divided into six major regions, namely Europe, South America, Asia, Africa, North America and Oceania.

The number of places in the final stage of the World Cup is 32, and the host country in the final stage can directly obtain the quota in the final stage, except for the host country, the other places are allocated by FIFA according to the football level of each qualifying region, and different qualifying regions will have different numbers of final stage places. Note: FIFA stipulates that from the 2006 World Cup qualifiers, the defending champions will need to participate in World Cup qualifiers in their own region, so that only the host nation can qualify for the round of 32 of the finals.

The host country of the World Cup finals must be a FIFA member state (region), and the member state (region) needs to apply to FIFA (two members can jointly apply to host it), and then the vote of all FIFA member countries (region) will be selected.

The 32 teams will compete for the championship in the final stage of the tournament in the host country. In the final stage, 32 teams will be divided into 8 groups of 4 teams in each group through the draw, and the top two teams in each group, a total of 16 teams, will qualify for the semi-finals; After entering the rematch, the sixteen teams will determine the schedule according to the established rules, no more draws, and then play a single knockout match until the champion is determined.

Girth: The FIFA standard is cm; Jabulani is cm

Roundness: To measure the diameter in 16 different places on the ball, the FIFA standard is the maximum error; Jabulani is.

Water absorption: Squeeze and flip the ball in water 250 times, the FIFA standard is a maximum weight gain of 10%; jabulani is 0%.

Heidi: This one is so strong! ）

Weight: The FIFA standard is 420-445 grams; Jabulani is 440+ - grams.

Consistency: Throw the ball from a height of two meters to a steel plate 10 times, the difference between the lowest and highest points is 10cm, and the distance between 143 and 149cm each time is between 143 and 149cm.

The official match ball "jabulani" for the 2010 World Cup in South Africa. FIFA approved eligibility criteria: soccer weight between 420 445 g Adidas "jabulani": soccer weight 440 g (+ - 2 g).
