      Lots of them! Last wefek I had to measure the mass of some parts (a camera and a lens) with a mass balance so I could include the weight in my report. I use rulers a lot to measure lengths, to see i things fit with others, and often I’ll just hold a ruler up in the air and try to get an idea of how big 40 millimeters is! (<-you might try this 😉

      I have to make lots of measurements at work. For example, if I’m testing an electronic circuit I have to check all the different electronic signals are correct. There’s a document which tells me what voltage range each one should be in, so I use something called an Oscilloscope to measure the voltage levels to see if they’re correct. If the circuit is going into space then I have to do all this in a clean room, and I have to wear gloves, a face mask, hair net and gown! It’s not very comfortable!

      Good question!

      I use all sorts of measurements. The obvious one is length; whenever I have to make anything, it’s important that it fits into the space available, or is long enough to reach between two things that need connecting.

      I use various machines to help measure the properties of RF cables and devices. That means I’m using measurements of voltage and time, even current – although to be fair, the machines make those measurements and I use the results.

      Temperature is important in the running of the machines I work with – especially if they end up getting too hot!

      There’s water and gas used for cooling and that has to be monitored in terms of pressure and speed.

      I even sometimes have to measure sound levels to make sure it’s safe to work near the machines.

      That’s a long answer to say: “All sorts!”
