parts

In science and engineering, the parts-per notation is a set of pseudo-units to describe small values of miscellaneous dimensionless quantities, e.g. mole fraction or mass fraction. Since these fractions are quantity-per-quantity measures, they are pure numbers with no associated units of measurement. Commonly used are parts-per-million (ppm, 10−6), parts-per-billion (ppb, 10−9), parts-per-trillion (ppt, 10−12) and parts-per-quadrillion (ppq, 10−15). This notation is not part of the International System of Units (SI) system and its meaning is ambiguous.

    Group advice sought - been without my car for 5 months.

    Afternoon all. On a sunny day in September 2023, I opened the roof on my 22 reg ZS SR Trophy and there was a horrible scrunching sound, the roof blind had somehow detached itself from the runners and failed. I've had a few cars with glass roofs so I'm aware of how they work, never had this...

    Does MG5 share mechanical parts with other cars?

    Two years of driving my MG5 LR taxi over speed jumps has done some part of my suspension in. The official MG garage won't see me for a month! So I'm parked outside my old ICE mechanic waiting for a ramp. He's already said he doesn't think MG parts are available in my country (Ireland). My only...
