    Conversion Chart: U.S. to Metric

    Published: Apr 25, 2021 · Modified: May 11, 2025 by Petra Kupská | Cook Like Czechs · 9 Comments

    In the Czech Republic and across most European countries, cooking ingredients are weighed on a kitchen scale. We use metric units, most often grams for mass and milliliters for basic liquids.

    My recipes on this blog are based on the originals written in metric units. To adapt to the U.S. measuring system, I use the following conversions according to FDA guidance:

    • 1 US legal cup = 240 ml
    • 1 Tbsp = 15 ml
    • 1 tsp = 5 ml
    • 1 fluid ounce = 30 ml
    • 1 oz = 28 g
    • 1 lb (pound) = 454 g
    u.s. cup flour to metric scale

    Below you will find the most commonly used ingredients converted from U.S. units to the metric system. I weighed each ingredient on my kitchen scale to make sure the conversions listed in the recipes are correct.

      Hello Petra ~
      I want to THANK YOU for providing the above Metric/US Std measurements - so concise and thorough! I love to explore ethnic cooking and trying to figure out the above differences in recipes was a nightmare (I made so many mistakes!). I'm looking forward to trying your various creations .... Best Wishes ~ Ellen

        Hello Ellen, Thank you for your kind comment! I come from the Czech Republic, where we measure our cooking ingredients with a scale and use the metric system. When I started cooking for a US audience, I had to prepare a conversion for each ingredient used. If you need any advice on a Czech recipe, I'd be happy to help! 🙂 With warm greetings from Bohemia, Petra

        Hi Kamilla, 2.1/2 teaspoons of active dry yeast could be about 30-35g of fresh yeast. Good luck baking the kolache!
