International Softball Federation Playing Rules Committee Ball Standards 1. The final 30.5 cm (12 in) ball should have a surface area of 30.2 cm (11 7/8 in) to 30.8 cm (12 1/8 in) and a weight of 178.0 g (6 1/4 ounces) to 198.4 g. (7 ounces).

The average mass of a softball is not publicly available, but it's estimated to be around 350 grams (12 oz or 454.9 pounds). That's less than the maximum recommended weight of 360 grams (13 oz).

The fastest pitch in baseball is 100 miles per hour (160 km per hour), and the slowest is 50 miles per hour (80 km per hour). A softball thrown by an amateur player moves at **about 60 miles** per hour (95 km per hour). A professional player can throw a softball up to 70 miles per hour (110 km per hour). A baseball played at night has lights on the batter's box, on the home plate umpire's stand, and behind each base. These are called "nighttime lights." There are also lights on top of both dugouts; these are for visibility purposes only and do not affect how well a team can see its opponents during games.

A typical softball game lasts six innings with each team getting two turns at the bat. After every out, the runner who was standing near first base has the opportunity to advance one base if there is a runner on second.

12" tall Softballs come in a variety of sizes. Most leagues in fast pitch softball utilize a ball with a circumference of 12 inches (30 cm) and a weight of 6.25 ounces (177 g). Younger players often use an 11-inch (28-cm) circumference ball. Older players generally use a 10- or 9-inch (25- or 23-cm) ball.

A regulation softball is much bigger than a regulation baseball. A softball is 11.88 to 12.13 inches in circumference and weighs between 6.25 and 7.00 ounces; a baseball measures **9.00 to 9.25 inches** in circumference and weighs between 5.00 and 5.25 ounces. The extra weight of the ball provides more momentum when hitting it.

Baseballs are generally made from leather or synthetic materials while softballs are usually made from rubber. Both types of balls have similar spindly metal wires inside them to keep their shapes while they're being played with.

The difference between a baseball and a softball is that the softball is heavier and larger than the baseball. This means that it will travel farther when thrown and hit with the same amount of force as the baseball. Also, the ball is deadlier because you get less time to react to what happens on the field with each pass through the strike zone. These differences should be taken into account by players who want to know how far and hard their pitches will travel.

In terms of weight, a softball is about 1/4 to 1/3 more than a baseball. Because of this, softballs require **more speed** when throwing them so that they can reach **the proper velocity** required for **batting practice** or an actual game. As far as dimensions go, a softball is about 1-1.5 inches longer and wider than a baseball.

"The official softball is a smooth-seam ball with a circumference of 12 inches and a weight of 6.25 to 7 ounces (177 to 198 g)." (Source)

Mass of a Softball = 1.095 kg (2.4 lb)

Volume of a Softball = 38.8 in3 (966 cm3)

Convert mass to volume: M/V = KG/L

So, the factor Kg/L for a softball is 1095.

Now, how do you put this into practice? Well, if you have a softball that is 50% air, then its mass would be 1.095 kg and its volume would be 951 cm3. If you divide **the two numbers** you get 1.545, which is very close to **the actual value** of 1.571.

So, going by this example, it can be seen that a softball has about 1.5 times more volume than mass. This means that it is an elastic body and so any force applied to it will eventually be spread out over a larger area.

What is the weight of a softball? Official 12-inch softballs range in weight from 6.25 to 7 ounces (177 to 198 grams). There is also a 16-inch softball that weights 9 to 10 ounces and is popular in Chicago and other Midwest cities (255 to 283 grams).

The weight of a softball depends on how it is made. If it's made of **synthetic materials**, it should be noted on the ball's packaging. If it's made of natural rubber, its weight will typically be less than 7 ounces (198 grams).

The weight of a softball is important because it determines many of the rules that apply when playing the game. For example, if you can throw or hit the ball **100 yards** in the air twice with **no additional help** from anything else, then it shouldn't be a problem for you to hit a home run.

But if your league uses **a weighted ball**, then you'll need to make sure you are able to throw or hit the ball 100 yards in the air at least once. Many baseball fields have scales to measure how far you can throw a ball, and most allow you to use a driver such as a softball if you don't have a bat capable of hitting a hardball.

As long as you aren't too proud to accept help when needed, you should be fine.
