How much weight taken for a passenger in car during calculation?

Typically, the weight taken for a passenger in a car during calculations is around 150 pounds (68 kilograms) for an average adult. This value is used as a standard estimate for occupant weight in various engineering calculations related to vehicle design, performance, and safety.

It's important to note that the actual weight of passengers can vary significantly based on individual factors such as height, body composition, and whether they are carrying additional items like luggage. For more precise calculations, specific data on passenger weights may be used if available.

In automotive engineering, the weight of passengers is considered along with other factors such as the curb weight of the vehicle, cargo load, and fuel weight to determine the overall vehicle weight. This information is crucial for various purposes, including determining vehicle performance, fuel efficiency, handling characteristics, and structural design requirements.

Additionally, the weight of passengers can impact vehicle safety systems, such as airbags and seat belts, which are designed to provide adequate protection based on estimated occupant weights. By using a standard value for passenger weight, engineers can ensure that safety systems are designed to perform effectively under normal operating conditions.

It's worth mentioning that some jurisdictions may have specific regulations or standards that define the assumed passenger weight for certain types of vehicles or transportation scenarios. These regulations can vary and should be taken into consideration when performing weight-related calculations for vehicles.
