You know that moment when leadership asks, "How much are we spending on social video?" You pause - not because you don't know your campaigns, but because answering means: Pulling multiple reports. Reconciling mismatched labels. Piecing together data from different teams to get to a single number. That's not just a reporting headache. It's a sign your measurement isn't speaking the same language across teams and platforms.

This means these three values can't be independent; if you know two of them, you can derive the third. How do physicists deal with this? We define the speed of light as exactly 299,792,458 meters per second. (How do we know it's exact? Because we define a meter as the distance light travels in 1/299,792,458 of a second.) Then we measure the magnetic constant () and use that value along with the speed of light to calculate the electric constant ().

The newly designed Laboratory Campus of GUM in Kielce is a blend of precision metrology and scientific aesthetics, aiming to elevate Poland's status in international metrology.
