Into Unscientific

In the 21st century, the units of measurement used by countries are generally grams and kilograms.

But the concept of "gram" was actually proposed in 1795. At that time, Gaul defined it as equal to "the absolute weight of water at the melting temperature of a cube with a volume equal to a side length of one hundredth of a meter."

Therefore, in the seventeenth century, the constant balance system was still commonly used in Britain, that is, drams, ounces, pounds, and so on.

The constant balance system is different from the troy balance system in that one ounce in the constant balance system is equivalent to approximately 28.3495 grams, while the latter is 31.1034768 grams.

Through the conversion of the former, it can be concluded that the ten ounces mentioned by Xu Yun is just over 280 grams, about half a catty.

mentioned earlier.

The cost of manual tomato sauce is mainly sugar. A pound of tomato sauce requires about 30 grams of sugar, which is about 30 grams of sugar for 18 ounces.

The current market price of sugar is about 8 pence per 100 grams, but the cost price taken by the diocese is much lower, the price is only about 2 pence - you can refer to the internal price of tobacco or liquor, sugar is even more ruthless, Because it is loot.

So after some conversion, the cost of ten ounces of tomato paste is about 0.6p.

Counting other transport, labor and miscellaneous, it is about 0.8p left.

The cost of 0.8 is priced at 2 pence, which is actually considered cheap - according to the normal thinking, on the premise that others can quickly copy the product and enter the market, the higher the product price, the better.

But the Grantham Diocese is not a professional chamber of commerce after all, and the cloak of religion is doomed that they cannot deceive people too hard, otherwise the bad reputation will not be worth the loss.

So after some discussion, Yarlin finally set the price of ketchup at 2p for ten ounces.

When the market subsides in the future, this kind of premium will not be scolded too much - if it doesn't work, just use consecration. Ahem, bless this kind of buff.

"Ten ounces and two pennies."

Hearing Xu Yun's quotation, Tiffany Boli made a simple calculation in her heart:

At present, the per capita income in England is 0.65 guineas, which is 150 pennies, and it looks like you can earn one penny every two days on average.

The income of Tiffany Boley's family is a little higher than that of ordinary families. They can settle in Grantham, and the annual income of the whole family can reach about 1.2 guineas.

Thinking of this, Tiffany Boli looked at the jar next to her again:

"Is this a ten-ounce can?"

Xu Yun nodded:

"That's right, the standard ten-ounce weight."

Tiffany Boley nodded slightly.

Ten ounces (280 grams) of tomato sauce seems like a lot. Even if I use it to spread bread and potatoes every day, I don’t think I can finish it in ten days and a half months.

It is much more expensive than butter, but much cheaper than sugar, and even ordinary families can afford it.

So after a moment of hesitation, Tiffany Boley made a decision in her heart:

"Give me ten ounces, sir."

"okay!"

Xu Yun hurriedly fetched a bottle, and at the same time lowered his voice and said:

"Ma'am, this bottle of ketchup is freshly made. It is taken from the back. It is fresher than the others. Don't tell anyone else."

Tiffany Boli was thinking about whether she could make a counter-offer, but she was overjoyed when she heard this—she could see clearly that Xu Yun had indeed brought the can from the area behind.

Therefore, she immediately refused to pay back the price, and readily took out two pennies:

"Thank you so much, please keep these two pennies."

Xu Yun took the money politely, handed it to the parish staff around him, and watched them record the transaction with his own eyes.

Then he looked around, took advantage of the gap when no one came, and stuffed the can of tomato sauce in front of him into the empty space behind.

And just when Xu Yun finished the operation secretly, someone suddenly touched his left arm.

Xu Yun turned around and found a little girl the size of a beanie standing beside her at some point.

The one who can walk around here is naturally no one else, but William's youngest daughter, Lilani.

But at this time Lilani's hand was not cow dung, but a cup of hot water.

Xu Yun blinked, seemed to understand something, and pointed to himself:

"For me?"

Lilani nodded.

Seeing this, Xu Yun couldn't help being surprised:

Since the last meeting, this brat seems to be a lot more low-key and well-behaved?

That's fine—it's not that a girl must be quiet and conform to the Three Obediences and Four Virtues, but at least she shouldn't be a brat.

Then he took the water glass, glanced at it while blowing, and found that nothing messy was added to it, so he took a sip lightly:

"Thank you, Lilani."

Lilani was silent for a few seconds, and a word suddenly popped out of his mouth:

"Last time. Sorry."

After speaking, the former brat turned around and ran away with small steps.

Xu Yun couldn't help scratching his head:

"this kid"

Tiffany Boli's purchase process is just a microcosm of today's booth. With the guarantee of the parish, the William family easily sold the cans of tomato sauce without much effort.

Tasting-introduction-collecting money.

The whole process is that simple.

Three hours later, today's bazaar came to an end - this is just the end of today, and as usual, the bazaar will continue to open for another day tomorrow.

The St. Tidodia Church will temporarily vacate an internal area to provide traders with a temporary place to stay overnight.

In a sense, this is a bit like an exhibition where future generations will provide accommodation, and it is a means of stimulating the economy led by the government.

And just when Xu Yun was about to help clean up the venue, Mavericks suddenly pulled him aside mysteriously:

"Fat Yu, we're going to get rich!"

Looking at this patriarch with staring eyes, Xu Yun's curiosity also aroused:

"Oh? Mr. Newton, how much ketchup did you sell today?"

Maverick looked around vigilantly, and whispered a number:

"Nine hundred pounds!"

Hearing this number, even Xu Yun couldn't help but smack his lips:

"My boy, nine hundred pounds?"

Nine hundred pounds, or just over fourteen thousand ounces.

Based on William's 10-ounce cans, that's more than 1,400 cans of tomato sauce.

To know.

The resident population of the entire main city of Grantham is only 3-4,000 people, and even during the market period, the gathered population is barely over 20,000.

More importantly, a can of ketchup corresponds not to one person, but to a family!

Even if some rich people's repeated purchases are deducted, the purchase rate of ketchup this time will not be lower than 15%!

From this, it is also conceivable how big a market ketchup will have in the whole of Europe—of course, that attributive must not be ignored, a market that cannot be monopolized.

"The cost of a can of tomato paste is 0.8p, net profit 1.2p"

At this moment, Mavericks, who can be ranked among the top few in history, calculated basic mathematics in a very philistine manner:

"1400x1.2 is 1680, divided by 252 is 6.67 guineas, we get 2.2

God, it's only three hours, and it's only one Grantham! How long is a can of ketchup enough to feed a family? "

Having said that, Maverick patted Xu Yun on the shoulder heavily:

"Fat fish, I declare now that we are friends!"

Maverick's palm was a bit forceful, Xu Yun was caught off guard and almost staggered.

"Can you take it easy?"

Xu Yun muttered and rubbed his shoulders, and was about to raise his head to say something, when he felt a pause around him, and a long-lost prompt board suddenly appeared in front of him:

[Newton has regarded the 'Wallfacer' as a wine and meat friend, the novice task has been completed, the dungeon time has stopped, and it is about to return to reality! 】

Xu Yun:

"????"
