A Brief History Of Scales

If your only experience with scales involves cursing at them for lying to you, then you may be surprised to learn how prominent of a role they've played in human history.

If your only experience with scales involves cursing at them for lying to you, then you may be surprised to learn how prominent of a role they've played in human history. Everything from law to commerce has been shaped by scales, making them one of the most enduring — and useful — tools mankind has ever developed.

Drawings of scales date back to 3500 B.C.E. in Egypt, where they were used to mete out justice. However, the oldest actual specimen was found in the Indus River valley, near modern-day Pakistan. Likely used around 2000 B.C.E., this scale was simply a balance using two plates attached to a pole. To use it, you placed an object on one plate, and then piled the other one with weight-setting stones until you found its balance.

The Romans developed a model that used a hook, which eventually led to the creation of platform scales. However, their scales backfired on them after Rome was captured by the Celtic chief Brennus in 390 BC. He demanded 1,000 pounds of gold as ransom, and when the Romans complained that he used rigged measurements, Brennus tossed his sword on top of the weights and proclaimed, "Woe to the vanquished!"

The basic balance design would remain largely unchanged until the 15th century, when Leonardo da Vinci created the graduated dial scale, which could achieve automatic balance. His invention was improved upon by the French mathematician Gilles Roberval, who made it more accurate by devising a system to evaluate the lever it used.

The spring scale would follow a few decades later, the brainchild of British balance maker Richard Salter. This model used the tensile strength of a coiled spring to figure out the weight of a given object. Spring scales are still in use today, although their accuracy is questionable.

In the 20th century, electrical scales were introduced, which could deduce a weight by running a mild electrical current through the subject. This process is known as impedance, and can also be used to determine the ratio of fat and muscle that the subject possesses.

It remains to be seen what the future holds for scales, but one thing remains clear: they'll take their secrets to the grave if they know what's good for them.

Finding The Right Digital Scale For You

Before you can find the perfect scale for your needs, you must first determine what those needs are. Are you trying to track your weight loss goals? Do you need to measure out the exact amount of food you're consuming? Or are you trying to determine just how much that trout you caught weighs?

Before you can find the perfect scale for your needs, you must first determine what those needs are.

Once you know what you need it to do, you'll find it much easier to find the right model. Keep in mind, however, that most scales are designed with a specific purpose in mind, and aren't likely to be very useful outside of that very limited scope. So yes, you can step on your bathroom scale with that trout in your arms, but that measurement won't be nearly as accurate as one you'd get from a hook scale designed for weighing fish and game.

One of the first things to look at is the scale's capacity. Many of them cut off at a certain point, so you'll likely be disappointed if you try to weigh yourself on one that has a 30-pound limit. Likewise, you probably won't want to count calories using a large industrial scale, unless you're really trying to bulk up.

The scale's accuracy is also important. Do you need to know the measurement down to the ounce, or is a general ballpark figure good enough? Again, this will likely depend on its intended use, but just be aware that you'll likely pay more for greater accuracy.

Finally, take note of its size and where you expect to put it. Do you want to devote a good chunk of your counter space to a food scale? Are you okay with devoting precious garage space to an industrial scale? These are questions to ask before you buy, so that you're not scrambling to find a spot for your new toy after you've already gotten it out of the box.

If you take each of these factors into consideration when shopping, you're much more likely to find a scale that suits your needs. Just be careful, because a bad scale can really...weigh you down.

How To Use Your Digital Scale

Using a scale might seem like a no-brainer, but if you're not using yours correctly, it can really throw off your readings and sabotage your measurements. Now, obviously each scale will have its own instructions that you should follow; that being said, however, there are a few ways to ensure you get the most accurate results possible.

This is a basic step, but if you get it wrong, you're dead in the water.

You'll need a flat surface for your scale to rest upon before you get started. If it's laying at an angle, that will throw off the distribution of materials and undermine the readings. This is a basic step, but if you get it wrong, you're dead in the water.

It's important to calibrate it regularly, as well. Most models will come calibrated by the manufacturer, but even so, you'll want to check yours regularly. To do this, press the calibration button and wait for the display to zero out. Then, place a calibration weight on it for about five seconds, after which the unit should reset on its own.

You should also check to see if your particular scale can handle off-center weighing. Many units require the load to be placed directly in their center to give accurate readings, while others can determine correct weights even if the subject is in the corner.

Ultimately, scales are fairly simple machines, and it shouldn't take you very long to get the hang of yours. You'll soon be weighing everything you can get your hands on — and that can get you a lucrative job guessing weights at a carnival.
