Isn’t the answer to the question what the scale is? Is that clear enough? For many, the answer is whether our weight is measured in kilograms, grams or pounds, but is that the correct answer? Well, technically, just because a kilo or a pound is a measure of mass. However, the scale measures something else, which is actually a strength.
If you are moving into a wider technical area, you may also have to ask yourself whether it measures our weight or our weight, because weights and measures are different by definition.
What does the scale measure?
The answer’s not as clear as you originally thought, is it? The scales actually measure the power that, if you remember your high school science class, is measured in Newton. The scale first measures the downward force and converts it into kilograms or pounds.
How does he do that? How is the force measured? And how does he make Newton pounds?
The answer lies in the design of the scales we use. Almost all scales use springs that are hidden in the mechanical structure of the scale. These springs actually measure the force you exert on them when you stand on a scale.
What is the measuring force on the scale?
When you stand on the scale or place something on it, the force you apply on the scale reduces the size of the springs. The scale actually measures the size of the spring for the calculation of the force. The shorter the length of the spring, the greater the force you exert and therefore the weight you have.
The spring that uses the scale is connected to the dial, which is visible on each scale. As the size changes, the dial also moves and shows the actual weight. The digital scale uses state of the art technology to convert differences in spring size into the weight displayed on the screen.
What we need to measure: Weight or weight ?
But here’s the problem. Weight is actually the gravity that acts on our body or another object. The problem here is that the gravitational changes apply to different planets, right? For example, if you use the same scale on the moon, it will give you a different weight because gravity is much weaker than that of the Earth.
For example, if you weigh 70 kg on Earth, then you weigh only 11.6 kg on the moon. However, if you use the same scale on Jupiter, your weight increases to 165 kg due to the higher gravity on Jupiter. They weigh over two tons in the sun!
To make the distinction easier, you will find scientific definitions for weight and mass.
- Weight! Weight! Weight! Weight! Weight! Weight! Weight! Weight! Weight! Weight! Weight! Weight! Weight! Weight! Weight! Weight! Weight! Weight! Weight! Weight! Weight! Weight! Weight! Weight! Weight! Weight! Weight! Weight! It’s the amount of dust in our body or in an object.
- Weight: It is the measure of gravity when applied to a given object or mass.
Even if you have a different weight on Earth and on the Moon or on another planet, your body weight remains the same. This means that your weight may vary depending on where you use the scale, but not your weight.
Here’s another difference. A kilogram or pound is a unit of mass, not weight. Because weight is also a kind of force, the attraction of gravity on us, the weight measuring device is also Newton.
Despite the differences in weight and mass, they are also connected to each other. When you go back to your school’s science class, you’ll remember that objects attract masses, right? The greater the mass of the object, the greater the attraction.
Therefore, the following rule applies: the greater the weight, the more important it is. Since the force is directly related to the mass, you will put more force on the scale if you have more mass, and less force if you have less mass.
What does our scale teach us?
As mentioned above, the unit of measurement for weight or force is the Newton. Our scales show us the Newtons? No, it’s not. So it certainly doesn’t tell us anything about the weight.
On the other hand, the unit of measurement for mass is the kilogram or pound, the unit indicated by our scales. This means that our scale measures mass, even if it uses a mechanism that calculates the force you apply, but then converts it into kilograms.
You can also see this because our scales represent the measurement of our mass, but in fact they are a measure of strength or, in simple terms, weight. That’s obvious, because the same machine shows you another dimension on the moon.
Does your weight change when you travel to the moon? No, it’s not. This means that the scale will tell you the wrong mass measurement, because it is unable to convert weight into mass due to changes in gravity.
You can also perform another experiment by standing on the scale. If you hold your hands against a wall or something firm and apply a downward force, the value on the scale increases. Once again, your weight will not change, but your readings will increase due to the increased force on the scale.
Here’s a simple fact. More and more people get confused when they use scales with the same weight and mass. But it’s not. When we use the scale, we really want to know what our mass is, and that’s exactly what the scale tells us when the result is displayed in kilos or pounds.
But the scales don’t measure our mass. It simply measures the force that is our weight. It simply converts the measured values of the force we apply into units of mass for our understanding.
So, what actually measures the circumference? The answer is strength or weight, but what we read on the scales is the measure of our mass. However, you cannot use the same scale to measure your mass on another planet because you have to adapt the conversion from newton to kilogram to the gravity of each planet.
