Such traditional methods have several pitfalls, seeing as they are prone to mathematical mistakes and errors that can prove to be very expensive. Consequently, if you’re a contractor, architect, builder, carpenter, tradesperson, designer, or just about anyone who works with dimensions and needs accurate and fast results to complex mathematic calculations, it would be prudent to invest in the Calculated Industries 4020 calculator.

The calculator has a lot in common with its other construction calculator counterparts. Like the vast majority of them, it is equipped with a host of experimental features. You can, for instance, take advantage of the length, width and height keys to quickly figure out area, linear, volume and perimeter dimensions. In addition, calculating things like area, square yards, feet, inches, centimetres, metres, and millimetres is both a quick and effortless endeavour. Contractors working with weight will come to appreciate the product's built-in pounds, tons, kilograms and metric tons units.

With this calculator in their hands, estimators will no longer have to scratch their heads when finding board feet for lumber and the cost of each unit of the material they require on the construction site. Another major highlight of the construction calculator is the inclusion of convenient and time-saving “Paperless” tape feature. It works by allowing the user to roll back the previous twenty entries, double-checking them for errors and typos to ensure they use only the most accurate results.

Craftsmen, designers, fabricators, technicians, and woodworkers will find the ease of use and versatility immensely appealing. Whether you want to plan, build or assembly a construction project, irrespective of the scale, the construction calculator will always come through for you. It is lightweight and compact and can slip relatively comfortably into the back pocket of your pants, the toolbox, the glove compartment of your car, and your backpack. The remarkable portability, therefore, ensure you bring it with you to all the construction projects you're involved in. Also, it comes with some extra features like the auto shut-off feature that conveniently switches of the machine after being inactive for between 8 and 12 minutes. The rugged protective cover of the machine prevents moisture, dust and other destructive weather elements from penetrating into the machine, rendering it unresponsive.

It is by all accounts a great construction calculator for solving virtually all construction related calculations. It packs a broad array of experimental features to make the work of designers, craftsmen, woodworkers, and architects both straightforward and effortless. Working in and converting between different dimensions, areas, and volume has never been easier. Because it is lightweight and compact, it will fit with relative ease and comfort in different storage spaces like pockets, backpacks, glove compartments, and toolboxes. Plus, it has a limited 12-month warranty and boasts a budget-friendly price tag. With such impress instrumental features, the Calculated Industries 4020 Measure Master Pro Measurement Conversion Calculator is definitely a must-have.
  • Compact design to make it more efficient
  • Easy to use
  • Powerful performance with complex construction-math calculations
  • The buttons are delicate

Criteria for Choosing the Best Construction Calculators


Having the right tool or machine is key to succeeding in any endeavour, and this also applies to the construction industry. Construction calculators come with a wide range of performance features to allow the user quickly, accurately and efficiently solve virtually construction-related calculations. Whether it’s linear, volume, take-offs, linear velocity, area, volume, weight, and weight per volume, the rate of flow, temperature, or just about any other calculations, you need a product that will always deliver. The construction calculator should similarly be able to convert between different standard United States (U.S.) units like yards, inches, fractions, metres, centimetres, millimetres in addition to metric and decimal. You need a construction calculator that can do these and so much more quickly and powerfully.


Convenience features are those that take the effort and time away from doing complex calculations, and construction calculators, at least the worthwhile ones, come with a bunch of them. It should be both lightweight and compact to fit comfortably and securely in the hand without slipping off. Some buttons are dedicated explicitly for performing specific functions or mathematical calculations, which makes them easy to find on the keypad. Similarly, those that do closely related functions are usually grouped together, so you’re not looking at a massive array of confusing buttons. Third, some products come with the backspace key, allow the user to roll back to previous twenty entries using the “paperless” tape feature, and even give the user the freedom to save their user preferences.

Ease of Use


Usability encompasses a wide range of things. In the case of construction calculators, the user needs to pay attention the design. Lightweight and compact units are very portable, they don’t burden the hands with too much weight, and fit with relative ease in the hands. Also, the display should be visible so that you can see the measurement readouts without straining your eyes and from several angles even with the screen tilted. A practical construction calculator needs to as have several memory slots to spare the user the frustration of having to memorize long strings of numbers. The ability to roll back to previous entries allows the user to compare figures and result, do a double-check, and ensure accuracy.


The vast majority of construction sites where architects, designers, engineers, and builders use construction calculators are open settings. Consequently, they increase the product’s exposure to several destructive environmental hazards like dust, moisture, rain, ice, and several others. Additionally, a construction calculator can easily fall on an abrasive surface and break up instantly. To prevent such adversities, it would be prudent to invest in a rugged and durable unit made with high-quality materials so that it can withstand the heavy use in the busiest environmental settings. These and several more are some of the factors you’ll have to keep in mind to get the most suitable construction calculator.

Frequently Asked Questions

Q: How are construction calculators powered?

A: Virtually all handheld construction calculators are battery-powered. The difference, though, lies in the type and number of battery they use. While have slots for just a single battery, others, on the other hand, have two slots, meaning that they won’t work unless the second slot is taken up by a similar battery. Also, different construction calculators use different batteries. While we’re still on the issue of batteries, it’s worth bringing to your attention the fact that a battery typically lasts for a considerable amount of time. Depending on the intensity of use, you might have to change the battery just once or utmost twice in the course of the product’s useful life.

Q: Do construction calculators come with warranties?

A: Most construction calculators provided the user with a warranty. Typically, it lasts for twelve months on average and is usually limited. You’ll have to do for the particular model you intend to buy, though, as the length and provisions of the warranty differ from one manufacturer to another.


The first step towards being a successful and productive architect, builder, contractor, designer, carpenter or engineer is investing in the most suitable and high-performance construction calculators. They come handy when the user is faced with long strings of numbers whose calculation by conventional methods would be laborious, tasking and time-consuming. They should similarly be easy to use, versatile, and rugged enough to withstand heavy use. All the construction calculators featured on our list are those things, and even more. Plus, they are fairly and reasonably priced.
