No single US measure holds 100 mL. The closest set is 1/3 cup + 1 Tbsp + 1 tsp, or 6 Tbsp + 2 tsp if you only have spoons. Both come to 98.6 mL, short by less than a third of a teaspoon.
For water, 100 mL weighs about 100 g, so a kitchen scale in grams is the most precise way to get it. In a metric-cup recipe from Australia, New Zealand, Canada or the UK, 100 mL is 0.4 of their 250 mL cup, a little under half.
100 mL also matters at the airport: TSA allows carry-on liquid containers up to 3.4 oz (100 mL), and 100 mL works out to 3.38 fl oz. See 3 oz to cups for travel bottles.
