To convert feet and inches into just inches, you need to understand that there are 12 inches in a foot. So, if you have a height of 5 feet and 8 inches, you can perform the following calculation:
1. Start with the feet: 5 feet x 12 inches/foot = 60 inches.
2. Then add the remaining inches: 60 inches + 8 inches = 68 inches.
Therefore, a height of 5’8″ is equal to 68 inches.
