What is 1-43?

1-43 is a scale used for model cars and is also known as the "O" scale. In this scale, one unit of measurement on the model car represents 43 units of the actual car. For example, if a real car is 4.3 meters long, the model of that car in 1-43 scale will be 10 centimeters long. This scale is commonly used for diecast model cars and is popular among collectors and hobbyists. Models in this scale range from vintage cars to modern sports cars and can be found in various brands and designs.
