Lightning Feats Value

[Damage3245]

Just noticed this while refreshing myself on Lightning feats and our standards for them.

According to the Lightning Feats page, we are supposed to use 4.4×10^5 m/s, or in other words, 440,000 m/s for the average speed of lightning. In brackets after this, it says (Mach 1294).

But according to Unit Conversion websites, 440,000 m/s = Mach 1,282.798834.

So... if the m/s value on our page is right, shouldn't the bit in brackets say something like (Mach 1282.798834), not (Mach 1294) which is a higher value?

This shouldn't really affect any calcs if they're using the m/s value in the formulas, but if any calcs use the Mach 1294 value instead, then there will be a slight inaccuracy.

First since I got here before anyone I deserve likes

Yeah, speed of sound should be 343.2 m/s or something, so Mach 1282 should be the correct value.

It's 343.2 m/s and not just 343 m/s? I've been lied my whole life!

Exact speed of sound kinda varies with atmospheric conditions tbh. Many sources just say 343... probably because more precise values are rather pointless.

Seeing how simple and straightforward this is, I don't think we need any big staff response to this thread, but one other staff member confirming that it is okay to update the page would be nice.

@Antvasima You okay with this?

343.2

This urks my OCD

 

[Antvasima]

This is perfectly fine and uncontroversial to apply, yes.

 

[Damage3245]

Cool. Applying the change now and will close this thread.

 

[Antvasima]

Okay. No problem. Thank you for helping out.
