How Long Is 25 Millimeters

Download Article

A millimeter (or millimetre) is a unit of measurement of length used to brand standardized measurements every bit part of the metric system. One millimeter is 1 1-thousandth of a meter. At that place are a couple means to mensurate millimeters. The first and simplest method is to employ a metric ruler, which is conveniently labeled with millimeter markings. The 2nd is to use basic math to catechumen another unit of measurement, such as centimeters, kilometers, inches, or yards, into millimeters.

1
Look at the unmarked lines on a metric ruler. There are 2 divide units of measurements on a standard metric ruler—centimeters and millimeters. The numbered lines stand for to centimeters, while the unmarked lines betoken millimeters. If you expect closely, you'll notice that in that location are 10 millimeters in a centimeter.^[1]
- The medium-sized line at the halfway indicate between each numbered centimeter measurement represents half a centimeter, or 5 millimeters.^[ii]
- This aforementioned labeling scheme is too used on longer metric measuring tools, such equally meter sticks and tape measures.
2
Line upward the finish of your ruler with the object y'all want to measure. More specifically, identify the line marked "0" up against the far edge of your object. Make sure the ruler is directly and neatly aligned with your starting point.^[iii]
- If you lot're trying to find out how long your smartphone is in millimeters, you would arrange your ruler so that the "0" marking is even with i of the device'south horizontal edges.
- Not all rulers have "0"due south printed on them. If the one you're using doesn't, it's safe to assume that the terminate of the ruler to the left of the "1" indicates "0mm."

three
Multiply the centimeter measurement simply earlier the end of your object by x. Note the number of the last total centimeter measurement. Multiplying this number by x will convert the unit of measurement to millimeters and tell you how long your object is in millimeters up to this betoken.^[four]
- If the concluding full centimeter measurement reads 1, multiplying it by 10 would give you ten, since 1cm = 10mm.
Tip: One quick and easy way to multiply past 10 when you're working with integers (whole numbers) is to simply tack a "0" onto the end of the number.^[5]
4
Add the number of lines after the last centimeter marking. Now, count up how many unmarked lines there are beyond the end of your object. The reason this is necessary is because there aren't plenty millimeters to account for another full centimeter. Using the centimeter measurement to chop-chop calculate the bulk of the object'southward length in millimeters just saves time.^[6]
- If the object you're measuring is 1.five centimeters, multiplying 1 times 10 gives yous 10, and adding 5 gives you a total length of 15mm.
- If it'due south easier for you, y'all can also measure one centimeter past the end of your object and then subtract the number of millimeters in between. 2 centimeters (twenty millimeters) minus v millimeters equals 15mm.

Learn how other metric measurements work to hands calculate millimeters. As yous've seen, there are 10 millimeters in a centimeter. Similarly, there are 1,000 millimeters in a meter and 1,000,000 millimeters in a kilometer, which is ane,000 meters. In one case you lot understand the math, converting other metric measurements to millimeters is a relatively uncomplicated chore.^[seven]
- The prefix "centi" ways "hundred," signifying that a centimeter is one hundredth of a meter. Past the same token, "milli" mean "thousand," so a millimeter is one thousandth of a meter.
two
Multiply inch measurements by 25.4 to detect their length in millimeters. You may need a calculator for this i. Start by entering your inch measurement up to two decimal places (as in "6.25"). And so, hit the "x" push and dial in "25.4," as there are roughly 25.4 millimeters in 1 inch. When you hit the "=" push button, the number you get will be the aforementioned measurement, merely in millimeters.^[viii]
- Using the formula described above, 6.25 inches is equal to 158.75 millimeters.
- Translating inches to millimeters is a little tougher than making other conversions, since inches are imperial units and millimeters are metric.^[9]
Tip: It should be fine to limit your final measurement to the numbers on the left side of the decimal point. If you need to be extra precise, round off to the nearest hundredth of a millimeter (the 2nd number afterward the decimal).

Multiply measurements given in anxiety by 304.8. The idea here is the aforementioned every bit converting inches to millimeters. There are approximately 304.viii millimeters in an imperial foot, so multiplying the full number of feet by 304.viii will assistance you determine how long information technology is using the smallest metric unit of measurement of measurement.^[10]
- If you're v anxiety tall, you lot would be i,524 millimeters tall. That sounds a lot more impressive!
four
Use a conversion factor of 914.4 to get millimeters from yards. Zero new here. i yard is equal to about 914.4 millimeters. As a upshot, multiplying a chiliad measurement by 914.4 will instantly turn it into a millimeter measurement.^[11]
- The aforementioned bones principle that makes information technology possible to catechumen inches and feet to millimeters also applies here. There are 12 inches in 1 human foot, so 12 x 25.4 = 304.8; a yard has 3 anxiety, so 304.8 10 3 = 914.4, and so on.
- It's well known that the field of play on an American football field is 100 yards. What many might non know is that this amounts to a whopping 91,440 millimeters. Imagine trying to measure that out with a ruler!^[12]

Grab a normal credit bill of fare. Virtually credit cards (and other types of plastic cards) have a thickness of 30 mil, which comes out to around 0.76 millimeters (0.762 mm, to be exact). It isn't the about exact measuring tool, just it may be close enough for tasks that require you lot to take a crude idea of how something measures up in millimeters.^[13]
- If y'all don't have a credit menu handy, stack 10 sheets of eight ^one⁄₂ in (22 cm) x 11 in (28 cm) printer newspaper on peak of each other to become a layer that's about 1 millimeter thick. This may be harder to work with than a unmarried plastic card, though.
- A "mil" is a little-used imperial unit that corresponds to i thousandth of an inch, and is not to be confused with millimeters.^[14]
Alarm: Since this method isn't very verbal, you shouldn't rely on it when the precision of the measurements you're taking are of import.
two
Stand the carte up on a piece of paper beside the object you're measuring. Marshal the outer edge of the menu with your chosen starting betoken on the object. Imagine that the card is a ruler, and that the edge is the 0mm line.
- For this method, you'll essentially be adding up one millimeter at a time in order to discover the one of the object'due south given dimensions.
3
Use a pen or pencil to draw a thin line forth the inner edge of the card. Run the tip of your writing utensil downwards the card to trace a line long enough to be plainly visible. This marks a distance of 0.762 millimeters betwixt the end of the object and your first line.
- Y'all'll be drawing a number of lines quite close together, so employ light force per unit area to make the line as thin as possible. Sharpening your pencil or using a pen with an ultra-fine indicate will help.
four
Slide the card downwardly to the other side of the line and echo the procedure. This line will be ane.52 millimeters from your starting signal. Reset your carte on the far border of your 2nd line and draw another. Keep measuring and marking in small increments until you reach the finish of the object, so count upward the number of individual spaces.
- Make certain you count the spaces between the lines and not the lines themselves, since there will be 1 too many.
- To increase your precision a fleck, count every 4 lines every bit 3 millimeters full. This volition assist make upward the difference, since the card isn't exactly 1mm thick.

Article Summary X

To easiest by to measure millimeters is with a metric ruler or meter stick. If you have a metric ruler, note that the numbered lines represent centimeters and the unmarked lines represent millimeters. One centimeter is equal to 10 millimeters. Put the zero finish of the ruler at the starting edge and count the unnumbered lines after the last numbered marker. Then, add the values together. So if you measured 1 centimeter and five millimeters, you'd go 15 millimeters total. To learn how to estimate millimeters, keep reading!
