Caster sugar's closest American equivalent is superfine granulated sugar, which can be hard to find; it is also known as bar sugar, as it is used to mix cocktails. It is sold in 1 pound boxes under the Domino brand. You can make it by running regular granulated sugar for several seconds in the food processor with the metal blade; this grinds the sugar to a finer consistency (superfine).
You can make any recipe that calls for granulated sugar because caster sugar can be used to replace granulated sugar.
Granulated sugar shouldn't be used as a substitute where caster sugar is specified in a recipe; granulated sugar will be too coarse.
No, caster sugar is fine-ground granulated sugar. Confectioner's sugar is a mix of ultra-fine sugar and a starch; it is sometimes called icing sugar.
If you are measuring by weight, yes. If you are measuring by volume (i.e "cups"), not necessarily, since caster sugar has smaller grains and hence will "fit together" in the cup in a more compact way than granulated sugar will. This means that a cup of caster sugar will contain slightly more than a cup of granulated sugar will.
No, its not, icing sugar is a fine powder whereas caster sugar is grainy crystals. Chemically they are probably the same, but the grain size is different. Caster sugar and granulated sugar are the same though I think.
Caster sugar is called "superfine" sugar in the United States. Do not confuse with confectioner's (powdered) sugar to which cornstarch has been added.
Yes, you can use caster sugar instead of granulated sugar. However, be careful on the measurements. Use a little less caster sugar. Caster sugar is finer granulated sugar. It is not as fine as powdered sugar, but it is in between granulated and powder. Caster sugar dissolves more easily,so it is very beneficial in making meringues.
Both work equally well for muffins. The only difference is that caster sugar is ground a little finer than granulated sugar. Granulated sugar might take a little longer to dissolve, but it will work equally well.
Like granulated/table sugar, caster/or sugar comes from sugar cane or sugar beet Castor, or caster, sugar is exactly the same as regular granulated sugar, simply ground to a very fine flour-like consistency Please do not confuse castor/er sugar with confectioners, or icing or fondant sugar which contains 3% starch to prevent clumping You can make castor/er sugar yourself by blending or processing regular granulated table sugar for a few minutes Use it promptly to avoid clumping

The same weight should be used for either. Caster sugar is just a finer grain so it will make a smoother textured result than using normal granulated sugar. Try using a blender on normal sugar to make it finer if you can't get caster sugar.
Yes, you can use granulated sugar as a substitute for castor (caster) sugar in a cake. Caster sugar is a quick dissolving sugar. So it will be necessary to grind standard granulated sugar in a food processor before using as a replacement. A blender can also be used.
