Millilitres to US cups is a recipe conversion, and the US cup is a specific unit: exactly 236.5882365 mL, being half a US pint. It is not the 250 mL metric cup used in Australia and parts of Europe, and it is not the 284 mL Imperial cup — a recipe that says 'cup' means one of three different volumes depending on where it was written.

A jug marked in millilitres cannot be read in cups without this conversion. Two thirds of a cup is 158 mL — an amount no jug is marked for, which is why halving and thirding American recipes is awkward outside the US.
US labels use the 240 mL legal cup while measuring cups hold 236.59 mL. The 1.4% difference never matters in cooking and does matter if you are computing nutrition from a label at scale.
Converting to millilitres first makes scaling arithmetic trivial — 1.5 × 158 mL is easier and less error-prone than 1.5 × two-thirds of a cup.
Brew ratios are given per millilitre or per gram of water. A '6 oz cup' in coffee terminology is 177 mL, which is not a measuring cup at all — the word means something different again in that context.

The US customary cup is half a US liquid pint: exactly 236.5882365 mL. The US 'legal' cup used on nutrition labels is defined as exactly 240 mL, so a label and a measuring cup can legitimately disagree. The metric cup used in Australia and New Zealand is 250 mL, and an Imperial cup is 284 mL. All of these measure volume, which is a poor proxy for the amount of a dry ingredient — a cup of flour can vary by 20% depending on whether it was scooped or spooned.
Cooking tolerances are wide, so rounding a US cup to 240 mL is safe for almost everything except baking percentages and confectionery. What is not safe is treating a volume as a weight: for flour, sugar and other dry goods, weigh in grams instead. The cooking converter on this site applies real ingredient densities rather than a single conversion factor, which is the only correct way to move between a cup and a gram.
That is the Australian metric cup. A US cup is 236.59 mL — about 5% smaller. In a bread recipe, 5% on the water is a noticeable hydration change.
A cup of flour is roughly 120–130 g, a cup of granulated sugar about 200 g and a cup of honey about 340 g. There is no single cup-to-gram factor; the ingredient decides.
A US cup is 8 US fluid ounces of volume. It is not 8 ounces of weight, except by coincidence for water.

The milliliter (mL) is a Metric unit of volume.
The us cup (cup (US)) is a US unit of volume.
Exactly 236.5882365 mL, being half a US liquid pint. The 240 mL 'legal cup' used on US nutrition labels is a separate, slightly larger definition.
No. The metric cup used in Australia and New Zealand is 250 mL, about 5.7% larger than the 236.59 mL US cup. An Imperial cup is larger still at 284 mL.
500 mL is 2.11 US cups — just over two cups. Recipes that call for 'two cups plus a splash' are usually approximating a round half-litre.
One milliliter equals 0.0042267528 us cups.
