How Long Is 4 Millimeters

Download Article

A millimeter (or millimetre) is a unit of length used to make standardized measurements as function of the metric system. Ane millimeter is one ane-thousandth of a meter. There are a couple ways to measure out millimeters. The first and simplest method is to use a metric ruler, which is conveniently labeled with millimeter markings. The 2d is to use bones math to convert another unit of measurement, such equally centimeters, kilometers, inches, or yards, into millimeters.

Wait at the unmarked lines on a metric ruler. In that location are two split units of measurements on a standard metric ruler—centimeters and millimeters. The numbered lines correspond to centimeters, while the unmarked lines betoken millimeters. If you look closely, you lot'll notice that there are 10 millimeters in a centimeter.^[1]
- The medium-sized line at the halfway point between each numbered centimeter measurement represents half a centimeter, or 5 millimeters.^[2]
- This aforementioned labeling scheme is also used on longer metric measuring tools, such every bit meter sticks and tape measures.
ii
Line upward the end of your ruler with the object you want to measure out. More specifically, place the line marked "0" up confronting the far edge of your object. Brand sure the ruler is straight and neatly aligned with your starting point.^[iii]
- If yous're trying to observe out how long your smartphone is in millimeters, you would arrange your ruler then that the "0" marking is even with i of the device'due 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 end of the ruler to the left of the "i" indicates "0mm."

3
Multiply the centimeter measurement merely before the end of your object past 10. Note the number of the last full 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 signal.^[4]
- If the final full centimeter measurement reads 1, multiplying it past 10 would give you x, since 1cm = 10mm.
Tip: Ane quick and easy way to multiply by x when you're working with integers (whole numbers) is to merely tack a "0" onto the end of the number.^[five]
4
Add the number of lines afterwards the final centimeter mark. Now, count upwardly how many unmarked lines at that place are beyond the stop of your object. The reason this is necessary is because there aren't enough millimeters to account for another full centimeter. Using the centimeter measurement to quickly calculate the majority of the object's length in millimeters just saves time.^[six]
- If the object you're measuring is 1.5 centimeters, multiplying 1 times ten gives you 10, and adding 5 gives you a total length of 15mm.
- If information technology'south easier for you, you tin also measure one centimeter by the end of your object and then subtract the number of millimeters in between. 2 centimeters (20 millimeters) minus 5 millimeters equals 15mm.

Acquire how other metric measurements work to hands summate millimeters. As yous've seen, at that place are 10 millimeters in a centimeter. Similarly, there are 1,000 millimeters in a meter and i,000,000 millimeters in a kilometer, which is 1,000 meters. Once you understand the math, converting other metric measurements to millimeters is a relatively uncomplicated task.^[seven]
- The prefix "centi" ways "hundred," signifying that a centimeter is one hundredth of a meter. By the aforementioned token, "milli" mean "thousand," then a millimeter is one thousandth of a meter.
2
Multiply inch measurements past 25.iv to discover their length in millimeters. Y'all may demand a calculator for this one. Start by entering your inch measurement upwards to 2 decimal places (every bit in "6.25"). So, hitting the "x" push button and punch in "25.4," as at that place are roughly 25.4 millimeters in 1 inch. When yous striking the "=" push button, the number you become will be the same measurement, only in millimeters.^[8]
- Using the formula described to a higher place, 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: Information technology should be fine to limit your last 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 after the decimal).

Multiply measurements given in feet by 304.viii. The thought here is the aforementioned as converting inches to millimeters. There are approximately 304.8 millimeters in an regal foot, so multiplying the total number of feet past 304.8 will help you determine how long it is using the smallest metric unit.^[x]
- If you're 5 feet tall, you would be 1,524 millimeters tall. That sounds a lot more impressive!
iv
Employ a conversion factor of 914.iv to become millimeters from yards. Nada new hither. ane grand is equal to about 914.4 millimeters. As a effect, multiplying a yard measurement by 914.iv will instantly plow it into a millimeter measurement.^[11]
- The aforementioned basic principle that makes it possible to convert inches and feet to millimeters as well applies here. There are 12 inches in 1 human foot, then 12 x 25.4 = 304.8; a yard has 3 anxiety, so 304.eight x 3 = 914.4, and then on.
- Information technology'due south well known that the field of play on an American football field is 100 yards. What many might not know is that this amounts to a whopping 91,440 millimeters. Imagine trying to measure out that out with a ruler!^[12]

Grab a normal credit card. Near credit cards (and other types of plastic cards) have a thickness of 30 mil, which comes out to effectually 0.76 millimeters (0.762 mm, to be exact). It isn't the nigh exact measuring tool, but information technology may be close enough for tasks that require yous to take a rough idea of how something measures upward in millimeters.^[13]
- If you don't have a credit card handy, stack x sheets of 8 ¹⁄₂ in (22 cm) 10 xi in (28 cm) printer paper on acme of each other to become a layer that'southward about 1 millimeter thick. This may be harder to work with than a single plastic bill of fare, though.
- A "mil" is a piffling-used imperial unit that corresponds to ane thousandth of an inch, and is not to exist dislocated with millimeters.^[14]
Alarm: Since this method isn't very exact, you lot shouldn't rely on it when the precision of the measurements you're taking are important.
ii
Stand the card upwards on a piece of paper abreast the object you're measuring. Align the outer edge of the card with your chosen starting bespeak on the object. Imagine that the carte du jour 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 find the one of the object'south given dimensions.
3
Use a pen or pencil to depict a thin line along the inner border of the card. Run the tip of your writing utensil down the card to trace a line long enough to be manifestly visible. This marks a distance of 0.762 millimeters between the end of the object and your starting time line.
- You'll be drawing a number of lines quite close together, and so use light pressure to make the line as thin every bit possible. Sharpening your pencil or using a pen with an ultra-fine betoken will help.
4
Slide the card down to the other side of the line and repeat the process. This line will be ane.52 millimeters from your starting point. Reset your card on the far edge of your 2nd line and depict another. Continue measuring and marking in small increments until you accomplish the end of the object, and so count up the number of individual spaces.
- Make sure you count the spaces between the lines and non the lines themselves, since there volition be ane as well many.
- To increment your precision a bit, count every 4 lines as 3 millimeters total. This will help make up 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 take a metric ruler, note that the numbered lines represent centimeters and the unmarked lines correspond millimeters. Ane centimeter is equal to 10 millimeters. Put the nada end of the ruler at the starting edge and count the unnumbered lines later the last numbered mark. Then, add the values together. And so if you measured 1 centimeter and five millimeters, you'd become 15 millimeters total. To larn how to estimate millimeters, proceed reading!
