Much of the world around us would be a mystery without good measurements. Whether it’s the depth of the ocean, the nutrients in your cereal, or the age of dinosaur fossils, measurements enable us to learn about our world and make good decisions about what to do in everyday life. In our “How Do You Measure It?” web series, we answer questions that will help you better understand how our modern world works — and why good measurements play an important role in your life.
Do you have a question you'd like us to answer? Contact HDYMI editor benjamin.stein [at] nist.gov (Ben P. Stein) and your question could show up in a future update to this site!
