Gadget

I do love a gadget. My car told me I had an under inflated tyre yesterday. I pumped it back up, but the gauge on the mini compressor is in kg/cm². Means nothing to me. I think in decimal with most things, but that sort of conversion is best left to maths teachers and rocket scientists. I used to have a little widget to measure the tyre pressure in psi, but it has been lost in the sands of time. So for the sake of a fiver, I’ve ordered a new one.
