it weights objects
Some examples of spring scales include handheld luggage scales, kitchen scales, and fishing scales. These devices use the elasticity of a spring to measure the force exerted on them, providing a reading of the weight of an object.
The spring scales are attached in series. The weight of the object will be distributed between the two spring scales, causing them to deflect. The sum of the deflections of both scales will give the total weight of the object. Since the mass of the spring scales is negligible, they will not significantly affect the measurement.
measurement
Spring scales can be calibrated in any desired unit of force. Some examples are: -- newton -- ounce -- pound -- ton -- stone
The unit used on spring scales is 'Newtons.'
To measure mass.
Spring scales can measure grams, newtons, or pounds.
Balance, spring, inertial.
The spring balance scales were invented by Richard Salter, a British balance maker, in the late 18th century. He developed these scales to provide a portable solution for measuring weights accurately.

Spring scales are commonly used to measure weight because they operate based on Hooke's law which states that the force required to extend or compress a spring is proportional to the displacement of the spring. This makes them ideal for measuring weight as the force exerted on the spring by an object can be directly correlated to its weight. Additionally, spring scales are generally portable, easy to use, and cost-effective.
When you pull on the scale you stretch the spring the pointer on the scales moves as you pull to measure the force you are using you have to be able to lift or pull on the spring scale
