Correct Answer - Option 4 : Cubit

Measurement is the comparison of an unknown quantity with a known quantity.

• Standard Unit of Length: When a unit is accepted by the majority of people, it is called a standard unit of measurement. Example, kilogram, metre, etc.
• Non-Standard Unit of Measurement: Those units which are not accepted by the majority of people are called a non-standard unit of measurement. For example,
• Fathom: It is used for specification in marine depth, usually, 1 fathom (ftm) = 6 feet = 1.8288 metres
• Handspan: When your fingers are stretched out, the length between your little finger and thumb is called a handspan.
• Cubit: The length from your elbow to your middle finger is used for measurement
• Finger: Smaller objects can be measured using finger

Hence, we conclude that the length of your arm from the end of your middle finger to your elbow used as a nonstandard unit of length is known as a cubit.
