Measurements and conversions Posted by on Oct 27, 2012 in Regulations

A lot of people get confused about different measurements used in different countries, so I decided to write this post to help a little bit. To be honest, I still have to think a while before converting everything, after spending most of my life in Poland and living here in the States for 10 years…

Like most European countries, Poles use the metric system.

Distances are measured in meters and kilometers.

1 m (meter) = 100 cm (centimeter)

1000 m = 1 km (kilometer)

Fluids are measured in liters, weight in kilograms and temperature in degree Celsius.

1 l = 1000 mL (millilitre)

1 kg (kilogram) = 100 dg (decagram) = 1000 g (gram)



1 inch = 2.54 cm

1 foot = 30.5 cm

1 yard = 0.9 m

1 mile = 1,609 m


1 pound = 454 kg

1 ounce = 28 g


1 US fl. oz. = 29 mL

1 US pint = 473 mL

1 US gallon = 3.8 l

1 UK fl. oz. = 28 mL

1 UK pint = 368 mL

1 UK gallon = 4.6 l


-17.8 °C = 0 °F

0 °C = 32 °F

37 °C = 98.6 °F

100°C = 212 °F

Did you know that Gabriel Fahrenheit was born in Gdańsk in northern Poland?

My name is Kasia Scontsas. I grew near Lublin, Poland and moved to Warsaw to study International Business. I have passion for languages: any languages! Currently I live in New Hampshire. I enjoy skiing, kayaking, biking and paddle boarding. My husband speaks a little Polish, but our daughters are fluent in it! I wanted to make sure that they can communicate with their Polish relatives in our native language. Teaching them Polish since they were born was the best thing I could have given them! I have been writing about learning Polish language and culture for Transparent Language’s Polish Blog since 2010.

    You’ve missed out the cursed american cup.
    Also what is a stick of butter?

    When i look at american recipies (like rachel ray) and they have these measurements – i am completely lost!

  2. Konrad:

    A common unit for mass in Poland is “deca” (for decagram) which means 10 grams. This is even very unusual for people from other “metric” countries…
