I mean, the simplest answer is to lay a new cable, and that is definitely what I am going to do - that’s not my question.
But this is a long run, and it would be neat if I could salvage some of that cable. How can I discover where the cable is damaged?
One stupid solution would be to halve the cable and crimp each end, and then test each new cable. Repeat iteratively. I would end up with a few broken cables and a bunch of tested cables, but they might be short.
How do the pro’s do this? (Short of throwing the whole thing away!)
The actual unit is lower case, the multiplier is uppercase.
Wouldn’t agree with that… There are many different units and multipliers. the letter being uppercase or lowercase has nothing to do with it.
Examples:
letters for prefixes/multipliers being uppercase and lowercase: P, T, G, M, k, h, da, d, c, m, u, n (trillion, billion, million, thousand, hundred, ten, one tenth, one hundredth, one thousandth, one millionth, one billionth)
Letters for units being uppercase and lowercase: s, m, g, N, W, J, A, K, V, h, Hz (seconds, meter, gram, Newton, Watt, Joule, Ampere, Kelvin, Volt, hour, Hertz) (just recognised, that most units, which are named after scientists, are written with capital letters…)
km = thousand meters/kilometer
K = Kelvin (unit for temperature)
M = Mega (prefix for one million)
kJ = thousand joules
s = second
ms = millisecond (one thousandth)
S = siemens (electrical conductivity)
mS = milli siemens
mm = millimeter (one thousandth of a meter)
Mm = megameter (one million meters or thousand kilometers)

What is an M? Miles? That doesn’t seem right.
M = meters. Mi = miles
m = meters. M = mega (x 1 000 000).
That’s why Km is 1 thousand meters and Mm is 1 million meters.
The actual unit is lower case, the multiplier is uppercase.
For reals? Where can I read more about this?
Edit: nevermind, I just googled it. TIL!

It’s also a lower case k in km.
