How To Dial Scale Vs Digital Scale

Vernier Caliper


  • Typical resolution is 0.001″ (0.02 mm) and accuracy is 0.001181102″ (0.03 mm).
  • In general, it’s relatively the most affordable compared to the dial and digital calipers
  • Durable, especially those which are made of stainless steel
  • No power source is needed, can be used anytime
  • Reliable accuracy as long as having good eyesight and improved caliper material
  • Displayed in both mm and inch. Some model has either metric (mm) or imperial (inch).
  • Usable in any condition: wet, dry, oily, near magnetic field, etc.


  • Slow reading, takes some steps to get the measurement result
  • The users have to be used with the two scales and figure out the total reading
  • More potential user errors such as improper eyesight angle (parallax error), etc.
  • Relatively tricky to calibrate, especially when the zero error happens.



What is the difference between analog, digital and smart scales?

Analog, or spring-based scales, work mechanically to measure the weight of an object.

A spring and plate move when you step on the scale

A spring and plate move when you step on the scale, and four levers help to evenly distribute your weight. The up-and-down movements of a mechanical scale becomes a side-to-side motion, which then turns the dial to show your weight.

Over time, springs in analog scales may develop gradual wear and tear, which can lower both their accuracy and reproducibility.

You may also find it harder to read precise numbers, since these scales have a lower display granularity.

Which one should I buy?

Buy an Analog Weighing Scale, When-

  • You don’t want to spend much
  • You don’t care about the 500gms difference
  • You are not looking to use it for an extended period.

Buy a Digital Weighing Scale, When-

  • You want to spend a moderate sum of money
  • You are looking for accuracy
  • You are don’t want other metrics of your body

Buy a Smart Weighing Scale, When-

  • You have no issue investing a reasonable sum of money
  • You are looking for accuracy in measuring weight with other body metrics
  • You want to keep track of your weight over a period of time

What technologies contribute to accuracy in smart scales?

Overall, the technology in digital scales has been shown to be more accurate than that in analog scales. In a BMC Public Health study entitled “Accuracy and consistency of weights provided by home bathroom scales,” researchers evaluated the accuracy of dial-type bathroom scales vs. digital scales. They found that “digital scales accurately weighed test loads, whereas dial-type scale weights differed significantly.”

Auto-calibration Auto-calibration consists of checking a weight measurement by comparison with a standard, in order to verify that the scale keeps the same references over time, and in temperature variations or even humidity. Gravity compensation Certain cellular scales or Wi-Fi connected scales sometimes have scale location information. This allows for more accurate calibration, which takes into account the acceleration of gravity at the location where the scale is used. Position control While detecting your weight distribution among the different load cells, small arrows in the corners of your scale’s screen show you where to stand for the best accuracy. Step-on & auto-zeroing If these features are user-friendly, the scale may “have fewer moving parts to get out of alignment or become damaged and have mechanisms to automatically set the starting weight to zero,” according to BMC Public Health. High-sensitivity load cells When it comes to digital scales accuracy, highly sensitive load cells enable the smallest voltage variation to be detected with the highest reproducibility.

Digital Caliper


  • Digital caliper has a greater resolution than vernier and dial calipers. On the market, typical digital caliper resolution is 0.0005″ and its accuracy is ±0.001″.
  • Super easy, instant, and fast reading
  • Functional buttons such as conversion button from mm to inch for happier measuring journey
  • Easy zeroing, the zero points can be changed easily as wanted
  • Suitable for those who have trouble with eyesight
  • Reliable accuracy, better resolution than vernier and dial
  • A particular digital caliper has an SPC cable slot to transfer measurement data to other devices such as smartphone, tablet, and computers
  • If it’s IP rated, it can be used in harsh environment.


  • Relatively the most expensive
  • Sensitive to the magnetic field, water, dirt, and oil
  • Not work without a power source (battery); you have to remove the battery if it will not be used for a long time
  • Need careful treatment

Digital Weighing Scales

Now, as we know that nothing is perfect as well as each new invention is for the betterment of the other one, so, after a while, a new weighing scale came into life, and that is the Digital Weighing Scale.

Digital scales are electronic, which display weight as a number usually on an LCD, i.e., Liquid Crystal Display. Discussing the advantages and disadvantages of the Digital Weighing scale that are as follows:


Digital Weighing Machines are priced in India from ₹800 to ₹1,200, and some premium scales are priced up to ₹2,000.

Digital Weighing Machines are the best choice for most people due to the pricing and the features they offer.

Advantages of Digital Weighing Scale:

  1. These scales have very excellent reliability because and each time they give you the perfect result as they get automatically calibrated after every time getting on.
  2. They are straightforward to use as they possess the quality of turning on and off themselves before and after the use.
  3. Such scales have excellent accuracy and durability, unlike the analog scales that get out of work after some time due to the loosening of the spring.
  4. There are some additional features in these scales, like the body composition or the Fat percentage and many more things.
  5. Scales are easy to carry and lightweight, unlike the analog scales, which are so much heavy to carry.

Disadvantages of the Digital Scale:

  1. The digital scales require a battery for their work, and there are many times when you need to check the weight urgently, but because of the unavailability of the array, you cannot.
  2. The prices of scales are comparatively higher than the analog one.
  3. Calibration of the scales is the topic of an issue as it is not easy to calibrate manually.

Digital Scale

These are new-age scales that show weight in numbers. They are sleek and portable. They are known to come in multiple variations with different functions. Let’s learn more about them:

  • Many digital scales are multipurpose. They can show other measurements like body fat. However, these come under the high-tech scales. The regular digital scales may only show weight, but we speak about multi-functional options to tell you that you have a large variety to pick from based on your preferences.
  • They are battery-operated.
  • Calibration could be the only downside of a digital scale. It can get confusing and tiresome to calibrate a digital scale.
  • These scales are accurate and can tell you exactly how much you weigh. They are usually preferred over the analog scales because of their precision.
  • They have a backlight, making it easy to read them.

You can see that where analog scales are easy to calibrate, digital scales are more accurate. At the end of the day, we honestly think accuracy matters more than anything else. That is why our vote goes to digital scales in the battle royale of digital vs analog scales.

However, you should understand that your search isn’t over yet. You need to dig deeper and choose the right brand and model for your needs. Whether it is analog scales or digital scales, you have many options, and some may not be reliable. So, we recommend that you check the reviews of a brand and find out how good it is before pressing the Buy button.
