      Yes. By the way, if you're trying to weigh a lathe, there are many
      other (potentially better) ways to go about this. The best would be
      to buy or rent a large spring scale which can be hung from a hoist or
      forklift. You can find ones in the 5 ton+ range. Or, you can get
      several load cells or reasonably high capacity scales and place them
      under the feet of the lathe.
      The easiest method IMO would be to try and get the weight from the
      manufacturer's literature. It is commonly included along with the
      dimensions and other specifications.
