• angles - then it means $'$ - angular minutes, $' '$ - angular seconds. Example: ${75}^{o} 20 ' 39 ' '$ which stands for: $75$ degrees, $20$ minutes and $39$ seconds.
• lengths - then it means: $'$ - feet, $' '$ - inches like: He is $5 ' 4 ' '$ tall. The sentence would mean : He is $5$ feet and $4$ inches tall. (about 165 cm)
