Spice question

Are the measurements below without batteries or case and with battery cover?

I checked my scales by weighing my mobile phone and it exactly matches the vendor specifications and is within the same range so I believe the scales are accurate.

HP-32E: 2134S, 217g
HP-37E: 2219S, 174g

Thanks to Steve for the simple weight metric, very handy.

I am trying to find the original source of the weights I quoted. So far I have only found quotes I have made
But to answer your question: "With the batteries installed the original press-fit version weighs about 220-230 g. The newer soldered version is lighter and weighs around 170-180 g." This should include the battery cover as well.
