## The Benefits of Knowing Your Height in Different Measurement Systems

Why do you need to know your height in different measurement systems? There are several reasons why this knowledge can be helpful:

• Traveling: if you are going to a country that uses feet and inches instead of centimeters, you might need to know your height in that system for filling out forms, buying clothes or shoes, or communicating with locals.
• Comparison: if you are trying to compare your height with that of someone who is used to a different system, you might want to convert your height accordingly to avoid misunderstandings.
• Interest: if you are simply curious about the differences and similarities between various measurement systems, you might want to know some basic conversion formulas and historical facts.
• Professional purposes: if you are involved in certain industries such as sports, health, or architecture, you might need to know your height or the height of others in both metric and imperial units for technical or legal reasons.

No matter what your motivation is, learning how to convert 170 cm to feet is a useful skill that can open up new opportunities and perspectives.

## The History of Feet and Inches

### Why Do We Use Feet and Inches?

The unit of feet and inches has been used for thousands of years in various cultures around the world. The reason for its popularity is partly due to its convenience for measuring human body parts and construction materials such as wood, stone, and metal. Unlike smaller units such as millimeters or larger units such as miles, feet and inches are easy to visualize and count without the need for complex tools or formulas.

In ancient Greece, the foot was based on the average length of a man’s foot, while in ancient Rome, it was based on the left feet of 16 citizens chosen by the government. During the Middle Ages, different regions in Europe had their own versions of the foot, ranging from 23.3 cm to 38 cm. It was not until the 18th century that the British Parliament standardized the measurement of the foot to be exactly 0.3048 meters, which is the value still used today in most countries that use the imperial system.

### How Is the Inch Defined?

The inch is a smaller unit that is based on the foot. In the British system, one foot is divided into 12 inches, so one inch is equivalent to 2.54 cm. The inch was first introduced by the Romans, who used it to measure fractions of a foot. In the 14th century, the inch was defined as the length of three grains of barley placed end to end. Today, the value of the inch is defined as exactly 2.54 cm, which makes it compatible with the metric system in terms of conversion.

## How to Convert 170 cm to Foot

### The Formula for Converting Cm to Foot

The basic formula for converting centimeters to foot is:

foot = cm / 30.48

This means that you need to divide the length in centimeters by 30.48 to get the equivalent length in foot. For example, if you want to convert 170 cm to foot:

foot = 170 / 30.48 = 5.577

This means that 170 cm is approximately equal to 5 feet and 7 inches. However, keep in mind that this is an approximation and might not reflect your actual height with high precision.

### The Formula for Converting Cm to Inch

If you want to know your height in both foot and inch, you can use a slightly modified formula:

foot = int(cm / 30.48)

inch = round((cm / 30.48 – int(cm / 30.48)) * 12)

The first formula divides the length in centimeters by 30.48 and rounds down to the nearest integer to get the value in foot. The second formula subtracts the integer part of the first formula from the original division result, multiplies it by 12, and rounds to the nearest integer to get the value in inches. For example, if you want to convert 170 cm to foot and inch:

foot = int(170 / 30.48) = 5

inch = round((170 / 30.48 – int(170 / 30.48)) * 12) = 8

This means that 170 cm is approximately equal to 5 feet and 8 inches. Again, keep in mind that this is an approximation and might not be accurate for everyone.

## Common Questions and Answers about Height Conversion

• Q: Why is there a difference between foot and inch in the US and UK?
• A: The US and UK use slightly different conversion factors for the inch. In the US, one inch is defined as exactly 2.54 cm, while in the UK, one inch is defined as exactly 2.54 cm divided by 0.999998. This small difference results in a conversion factor of 1.000002 for the UK inch. However, for most practical purposes, the difference is negligible.
• Q: Is there a way to convert between the metric system and the imperial system without using formulas?
• A: Yes, there are many online conversion calculators and apps that can do the conversion for you automatically. You can also use reference tables or memorize some basic conversion factors if you prefer to do it manually.
• Q: Do tall people always have longer feet or larger shoe sizes?
• A: Not necessarily. Although there is a correlation between height and foot size, it is not always a direct proportion. Some people might have longer toes, wider feet, or other factors that affect their shoe size independently of their height.
• Q: Can I convert my height to any other measurement system besides centimeters and feet?
• A: Yes, there are many other measurement systems in use around the world, such as hands, cubits, and paces. However, most of them are not widely recognized or standardized, so they might not be useful for practical purposes.
