First things first: I have the height and radius of the cylinder right? Well since this is a cylindrical sector calculator, I need to find the angle of the cylinder in degrees. I don't know the angle, what I do know is google can convert radians to degrees. I've been asking around, and it turns out I can find the rads by dividing the length of the arc of the sector by the radius of the circle. if the radius of the storm is 20 km, and goes out behind Pinkie for that same length, then that gives me an Arc length of 40 kilometers.

40000 / 965606.4 =

Converted to degrees =

When inserting the information into the cylindrical sector calculator, I get a volume of

Air has an average density of 1.225 kg/m3 (I have been informed that being 2 kilometers high will not change the density very much).

38624255991559.18 * 1.225 =

As noted in the assumptions section, I am assuming that the Rainboom began at 00.19.55 seconds, as that is when it interacts with the clouds. 40000 meters in 4.93 seconds is

0.5 * 4.7314714e+13 * 8113.59026^2 =

But we aren't done yet. This was only a small portion of the Rainboom. Shiba once did a surface area calc for the Rainboom that went something like this: ((2*pi*R)/7000 I do have a method of my own where I divide the surface area of the sector by the surface area of the entire Rainboom as a cylinder, but I'm not sure how accurate that would be, so I'll give out 2 ends for this based on both methods.

The feat happens in "Lesson Zero".

Celestia basically moves the Sun.

The diameter of the Sun is

From 3.135 to 4.874 the Sun moved

4.874 - 3.135 =

The Sun has a diameter of

140 / 50 =

Relativistic Energy seems like a good idea

The Suns mass is 1.989e30 kg, gonna plug that in with the speed

The episode: "Over a Barrel" shows the Mane 6 riding a train to Appleloosa. They began riding at an unknown time, but I do know for certain it was at least in the afternoon when the scene started. Later on we see it cut to nighttime, then morning where they are attacked by the buffalo. Afterwords, they finally arrive in Appleloosa at 2:00 PM according to the clocktower, with it's hands between the 1 and 3 pm mark. When we first see the train it appears to be in the afternoon, and they've definitely been riding for some time before we first see it since they're in the desert. So here's the timeframe: The sky when the train first appears in the episode is the same color as it is when they arrive at 2:00 PM the next day. So I'll assume it's roughly 2:00 PM when we see the train at the start of the episode. This is a 24 hour time-frame.

For those wondering about the relevance of Appleloosa, that's because of the official Map of Equestria, which depicts the Rock Farm as slightly farther than Appleloosa. This means that however far Appleloosa is, I can apply it to the Rock Farm which the blast wave of The Sonic Rainboom passed over.

Took me a lot of work, but I finally found a post saying that early steam trains would typically travel at speeds of 25 mph. This translates to

First, to find the size of the Minor, I need something to compare it to, like a pony. Luckily I can do exactly that.

First off: The height of ponies. https://derpicdn.net/img/2014/1/31/539446/large.png This is a size chart with Cheese Sandwich and other ponies in front of it. The taller ponies are around 4 ft tall (they seem to use the imperial system) from the very base of their ears. I'm going to use the smaller pony as the height of a mare. Now while it's true the smaller pony is probably a stallion, but the tips of this small stallions ears reach the base of the ears of a normal stallion next to him. Whenever we see a mare and stallion side by side, the mare's ear tips also reach the base of the stallions ears, so I think this is a safe assumption.

I started from where the ear meets the head and went from there. The smaller pony was difficult since their head was obscured by their mane but I found a rough estimate.

251 / 241 =

Left-hand pony is

4 / 1.04149378 = 3.84063745021 ft or

Twilight stands at 70 pixels, but I need to take into account that she is standing at an angle. Accounting for the angle, the height becomes 80. The snout is 48 pixels, and the head is 242 pixels.

242 / 80 =

1.170626294824008 * 3.025 =

80 / 48 =

1.170626294824008 / 1.66666667 =

0.702375775 / 0.0717131474 =

Applying square cube law: 9.79423998^3 * 450 =

Scales to Twilight for lifting the thing. I could establish the newtons needed to lift it against gravity, but I'm a lazy boi.

Now for the

45 / 34 =

1.32352941 * 3.541 =

Dividing this by the Kodiak's snout. 4.686 / 0.0717131474 =

Applying square cube law: 65.34^3 =

450 * 278957 =

Talk about massive. How the hell is something so heavy even alive? Scales to Rockhoof for tossing the thing and anyone remotely comparable to him (Lol, Rarity lifted more weight in clouds than this fraud). I could again, get something based on how high he tossed it, but I'm too lazy (plus I don't know any good time-frames or speeds).

Right, so the original method had been discarded as it was lowballing Rainbow's true speed. So I have to re-do the calc. Instead I'll be taking a timeframe based on Fluttershy, Twilight, and Spike walking from an unspecified location in Ponyville to Twilight's Library. It was afternoon when they began walking, and into Sundown by the time they got there. I've been told that 3 to 6 hours is a good assumption, so I'll be using these timeframes and a horses walking speed, which averages at 6.4 km/h according to this site.
