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!)
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.
It’s also a lower case k in km.
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)
For reals? Where can I read more about this?
Edit: nevermind, I just googled it. TIL!
