Is the ratio 1:1 by weight or volume?

Usually volume (1 cup couscous to 1 cup water), BUT weight is safer. 1 cup couscous is ~175g, while 1 cup water is ~237g. Following a weight-based recipe avoids dry clumps.

Couscous (Dry)

Couscous isn't a raw grain; it's tiny semolina pasta. Since it cooks by absorption (steaming off heat) rather than boiling, the weight-to-water ratio must be mathematical. Weighing ensures fluffy, separate grains every time, avoiding the dreaded clumpy or crunchy texture.

Grains

Rice, oats, quinoa, couscous and similar grains hydrate based on precise ratios. Volume is skewed by kernel size and air gaps. Weighing both dry and cooked grains keeps texture predictable.

Why weigh dry grains?Cup measures change with grain size and packing. Weight guarantees the right water ratio for fluffy, non-gummy results.
