Same idea, gives you a little more information and lets you disambiguate between similar measurements (e.g. US tablespoons vs. UK tablespoons).
Convert-Me - Cooking Ingredients : Converts to every well-known measurement at the same time.
Can convert (approximate) volume to weight and vice versa, for many ingredients. Food.com Measurement Converter : Same thing, a little easier to use, but slower.

If you are serious about cooking, buy some of the measuring cups with multiple different scales, similar to this one: Not only you will not have to convert the units, because many of the cups have both US and metric scales, but you avoid weighting flour, sugar etc.
Real time saver.

So, this is my first answer on stackexchange
and I'm new here.
Hello to the community :DThe answers above are very good, but I want to add one more app where the cooking units can be converted very quickly.
For example for cups, quarts or liter: 4 cups (US) to quarts (US) 4 liters to cups (US) For more conversions you can see the latest conversions of the volumes category directly on the website.

If you're trying to convert to metric, and you're getting your recipes from the web, you can also use a browser plugin I wrote which I believe is more convenient than the other suggested solutions, since it displays the conversion result directly in the recipe when you press a button:
Everything in […] was added by this plugin.
It also converts from volume to weight for many common ingredients (e.g. "10 tablespoons sugar" is converted to "125g").
The plugin is available for Firefox and for Chrome (free software with no ads.
I wrote it as a birthday gift :-).

I found a recipe that's using one or more measurements that I don't recognize. How can I convert it to a unit that I use locally?    Alternative question template: (to improve searchability): How can I convert an Imperial weight or volume measurement (tsp, tbsp, cups, ounces, pints, quarts, gallons, pounds) to an equivalent Metric measurement (g, kg, mL, L)?
How do I convert between the various measurements?

Rather than converting the units manually, use a browser plugin to convert them automatically or find a measuring equipment that has US and metric scales. You can either install an app or web plug that will convert the measurement for you in the recipe or buy a measuring cup that shows the different systems.
You can buy a measuring cup that shows imperial and metric measurements. There are apps and plug-ins that convert measurements for you.
