Difference in counters for spoons


I know that there are several types of counters of spoons/cups.

For example, a counter for cup is はい while another counter is カップ。

Also さじ and はい are also counters for spoons. What exactly are the differences
between these counters?




To count the number of spoons themselves in everyday life, **本【ほん】** is almost
always used (eg 5本のスプーン). さじ is rarely used for this purpose today, but
occasionally we see "ひとさじのスプーン" used as a bit poetic or literary expression.

To measure the amount of liquid/sugar/etc using a spoon, 杯【はい】 is mainly used
(eg スプーン3杯分の砂糖), and さじ is sometimes used alternatively (eg 砂糖3さじ).
