Exchange rate calculation and conversion
Suppose that the gold content of one pound is 7.32238g pure gold, and that of one dollar is 1.50463g pure gold. The cost of transporting one pound of gold between Britain and the United States is about US $0.03. Try to calculate the gold export point and gold import point of the United States

Sterling to USD seigniorage parity: 7.32238/1.50463 = 4.8666
Gold delivery point = coin parity ± unit gold freight
The US gold export point was 4.8669
US gold import point 4.8663

What's the relationship between gravity, weight and mass

Gravity is weight, gravity = mass times acceleration of gravity
The unit of gravity is Newton and the unit of mass is kg

What's the difference between mass and gravity

Mass refers to the amount of matter contained in an object. The force exerted on an object due to the attraction of the earth is called gravity. The unit is n, and the symbol is g. the formula is: g = mg '` on the earth, the relationship between them is mass, g = 9.8n/kg (about 10N / kg)

The difference and connection between mass and gravity
Difference 1. Concept 2. Direction 3. Symbol 4. Unit 5. Measuring tool
Contact: any contact is one!

The sign of mass is m
. gravity is g
And then
Mass is the content of an object. Unit: kg
Gravity is the effect of gravity on an object. Unit n
1kg=9.8N

Is gravity related to mass? Why?

About
Gravity g = mg
So the bigger m is, the bigger G is
G is the acceleration of gravity and 9.8m/s2 is the fixed value
