20 marlas = 1 kanal 

40 marlas = 2 kanal

Marla is among the land measurement units that are common in the Indian subcontinent. The unit, which is most used in the northern states of Punjab and Haryana, is not as popular as other local units such as bigha or gaj or international units such as acre or hectare. In these two states, one karam is 5.5 ft while one marla is equal to 9 square karams. 1 Marla is also equal to 9 Sarsahi. 20 marlas are equal to 1 Kanal.
