**Length conversion chart :**

"Customary units of length" is a system of measurements commonly used for length in the united states.

For measuring length, the U.S. customary system uses the inch, foot, yard and mile which are the only four customary length measurements in everyday use.

The relationship among the measurements inch, foot, yard and mile are given below.

**Example 1 :**

Convert 2 feet into inches.

**Solution : **

Here, we convert bigger unit into smaller unit. So we have to multiply.

2 feet = 2 x 12 inches

2 feet = 24 inches

Hence, 2 feet is equal to 24 inches

**Example 2 :**

Convert 3.5 yards into inches.

**Solution : **

**Here, we convert bigger unit into smaller unit. So we have to multiply.**

3.5 yards = 3.5 x 36 inches

3.5 yards = 126 inches

Hence, 3.5 yards is equal to 126 inches

**Example 3 :**

Convert 30 inches into feet.

**Solution : **

**Here, we convert smaller unit into bigger unit. So we have to divide.**

30 inches = 30 / 12 feet

30 inches = 2.5 feet

Hence, 30 inches is equal to 2.5 feet

**Example 4 :**

Convert 5280 yards into miles.

**Solution : **

**Here, we convert smaller unit into bigger unit. So we have to divide.**

5280 yards = 5280 / 1760 miles

5280 yards = 3 miles

Hence, 5280 yards is equal to 3 miles

**Example 5 :**

Convert 24 feet into yards

**Solution : **

**Here, we convert smaller unit into bigger unit. So we have to divide.**

24 feet = 24 / 3 yards

24 feet = 8 yards

Hence, 24 feet is equal to 8 yards

**Example 6 :**

David travels 60 miles in two hours. How many yards of distance will he cover in one minute ?

**Solution : **

Distance covered in 2 hours = 60 miles

Distance covered in 1 hour = 30 miles

We know that 1 hour = 60 minutes and 1 mile = 1760 yards

1 hour -----> 30 miles =====> 60 minutes -----> 30 x 1760 yards

60 minutes -----> 52800 yards

So, distance covered in 60 minutes = 52800 yards

Distance covered in one minute = 52800 / 60 yards

= 880 yards

Hence 880 yards of distance covered in 1 minute.

**Example 7 : **

Mark jogged 15840 feet in 45 minutes. Find the speed of Mark in feet per minute.

**Solution : **

Speed = Distance / Time

Speed = 15840 / 45

Speed = 352 feet per minute

Hence the speed of Mark is 352 feet per minute.
