A nopeuslaskija, also known as a speedometer, is an instrument used to measure and display the speed of a vehicle. It is a crucial component of modern vehicles, providing real-time information about the vehicle's velocity to the driver. Speedometers typically display speed in units such as kilometers per hour (km/h) or miles per hour (mph), depending on the region and the vehicle's settings.

The basic principle behind a speedometer involves the use of a sensor that detects the rotation of the vehicle's wheels. This sensor sends signals to the speedometer, which then calculates and displays the vehicle's speed. Modern speedometers often use electronic sensors and digital displays, offering more accurate and reliable readings compared to older mechanical speedometers.

In addition to measuring speed, some advanced speedometers also include features such as tachometers, which measure engine revolutions per minute (RPM), and odometers, which track the total distance traveled by the vehicle. These additional features provide drivers with comprehensive information about their vehicle's performance and usage.

Speedometers are essential for safe driving, as they help drivers monitor their speed and adhere to speed limits. They also play a role in vehicle maintenance by providing data that can be used to detect potential issues with the vehicle's drivetrain or wheels. Overall, the speedometer is a vital instrument that enhances the driving experience and ensures the safety and efficiency of modern vehicles.
