10 Best Micrometer Vs Caliper -Reviews & Buying Guide

Micrometers and calipers are two precision measuring tools in common use today. Since micrometers are more accurate than calipers, many people come to the mistaken conclusion that they’re only suitable for high-precision measurements. Because of this misconception, many manufacturers, engineers, machinists and hobbyists overlook the value that a micrometer has to offer.
Many people who use precision measuring devices like micrometers and calipers do not understand the differences between them. Let’s take a look at the difference between these instruments to help you figure out which is best for your project.

What to Consider Before Choosing the Best micrometer vs caliper

Accuracy

Micrometers are more precise than rulers. A micrometer’s accuracy is 0.0001′′, but a caliper’s accuracy is only 0.001′′. A micrometer is 10 times more accurate than a caliper because of this. Just keep in mind that there are cheaper versions of these tools available that are less accurate. Additionally, larger versions of these equipment would typically have reduced accuracy. A micrometer with a range of 17-18 inches and a caliper with a range of 0-24 inches may only be accurate to +/- 0.002 inches. To summarize, understand that precision varies, but in general, micrometers are 10 times more accurate than calipers.

Range of measurement

Micrometer set in case with reference standards by Starrett. Micrometers have measuring ranges of 1 inch. 0-1′′, 1-2′′, 2-3′′, and so forth. The most common measuring calipers cover a range of 0 to 6 inches. Larger variations with measuring ranges of 0-12′′ and 0-24′′ are also available. Other ranges, such as 0-4′′ and 0-8′′, are also available, but they are far less frequent. Because of the disparity in measurement ranges, a set of micrometers would be required to measure over the same range as a single caliper. Calipers have a wider range of measurement but are less accurate.

User-friendliness

When using a micrometer, extra caution is required to maintain the improved accuracy. The amount of force you use to close the micrometer, for example, can alter your measurement. Many micrometers include ratchet or friction stops to cope with this issue. Even temperature becomes important when working down to a tenth (machinist jargon meaning 0.0001′′). Temperature fluctuations cause metals to expand and compress. Most micrometers contain plastic bits that can be used to help shield you from the tool to protect against this.

Speed

Micrometers take longer to use than speed calipers. Jaws may open and close in a fraction of a second. To cover an inch of travel, micrometers must spin the thimble 40 times.

Expense comparison

A micrometer and a set of calipers are both relatively inexpensive. Take, for example, a Mitutoyo 0-1′′ micrometer and a Mitutoyo 0-6′′ set of calipers. The difference is that you’d need a 0-6′′ set of micrometers to cover the same measuring range as a pair of calipers. A excellent set of micrometers will set you back much more than a standard 0-6′′ caliper.
