# How Long is 9 Inches?

If you want to understand how long nine inches would look in a physical object, you could look to common household objects that measure close to nine inches to get a rough idea.

Alternatively, if you aren’t familiar with imperial measurements, you might find it easier to imagine nine inches after it has been converted into metric units. Here we will look at various ways of understanding how long 9 inches is.

## Nine Inches in Other Units

Different units of measurement are used as the primary unit of measurement in different countries around the world. If a country uses imperial measurements, this means it uses inches, feet, pounds, and ounces as its units of measurement. If a country uses metric measurements, it will use millimeters, centimeters, meters, kilometers, kilograms, and liters as its primary units of measurements.

The USA is one of the few countries on the globe that still uses imperial measurements, while the UK uses the metric measurement system. Canada officially converted to metric measurements in the 1970s; however, many people still find imperial easier to use, so you can expect both types of measurement units to be used in Canada.

If you are in a country that doesn’t use imperial measurements, you might find it difficult to comprehend how long 9 inches is, so here we have converted it into other measurement units to help you get a better idea of what nine inches would look like.

### Centimeters

Nine inches converted into centimeters (cm) is exactly 22.86cm.

### Feet

Nine inches converted into feet is 0.75 feet. This is because one whole-foot measures 12 inches; therefore, as 9 is three-quarters of 12, 9 inches represents three-quarters of a-foot.

## Things That Are 9 Inches Long

If you need to measure nine inches and you don’t have a ruler or tape measure to hand, then you can use common household items and objects to help you. Certain items, such as paper and money, will have specific standard measurements, so this can be really helpful in understanding measurements, while other items can have slight variations in their measurements, such as cutlery, but you can still use these items to work out a rough measurement in most instances.

Knowing the rough measurement of some household items can be really useful because it means you can then measure any length (within reason!) simply by using things you have in your wallet or in your kitchen drawer.

A good example of this is knowing that a quarter dollar coin measures just under an inch, so if you want to measure how long a small object is, you can just lay out a row of quarters next to it, and; however, many you have at the end is how many inches your item roughly measures. Here we will look at various items you probably already have that can help you understand how long 9 inches is.

### 3 Crayons

A standard crayon that you would find in a pack of children’s crayons will measure approximately three inches long. This means if you want to estimate nine inches in length, you can line up three crayons from top to bottom in a straight line. Be sure to use new crayons to do this because crayons that have been heavily used will, of course, be significantly shorter in size.

### Printer Paper

Standard printer paper in the US has a measurement of 8.5 inches wide and 11 inches in length. This means if you have a piece of printer paper, you can easily visualize how long nine inches is because it will be just a smidge longer than the width of the paper.

### Throw Pillow

Most people have some throw pillows on their sofa or on their bed as a decorative touch and also to help with comfort. The most common size of throw pillow is 18 inches by 18 inches, so if you want to estimate how long nine inches is, then you can visualize half of your throw pillow.

### Lunch Plate

Lunch plates can vary slightly in size depending on manufacturers and the design of the plate, but typically you can expect the average lunch plate to measure roughly nine inches in diameter. This means if you want to get an idea of how long nine inches is, then you can imagine the size of a lunch plate or go to your kitchen cabinet and actually look at the real size of one.

### Teaspoon

Like plates, cutlery can vary in size from manufacturer to manufacturer; however, the average length of a teaspoon is 4.5 inches. As 4.5 multiplied by 2 equals 9, you can lay out two teaspoons end to end to find a length of approximately nine inches.

### 10 Pound Sterling Coins

A one-pound coin, which is used as currency in the United Kingdom, measures 0.92 inches in diameter. To achieve a length of nine inches, you would need to line up nine-pound coins in a straight line. This would give you an exact measurement of 9.2 inches, which is a little over the attempted nine inches.

### 9 Loonie Coins (10.4)

A loonie coin, which is a one-dollar coin in Canadian currency, measures 1.04 inches across. To find nine inches, you could line up nine loonie coins next to each other in a row to get an ultimate measurement of 9.36 inches. This is a little over the goal measurement of nine inches but will provide you with a good idea of how long nine inches looks in reality.

### 10 Quarter Dollar Coins

A quarter coin in US dollars, also known as a 25 cent piece, has a diameter measurement of 0.955 inches. If you lined up 10 quarters in a row, you would get a total length of 9.55 inches. This is about half an inch over the goal measurement of nine inches and will be a good representation of how long nine inches is.
