Why do you need a metric system insteed in an English system?

Answer 1

You don't. The metric system is the international system of measurement. It was designed with several goals in mind. Neutral and universal Any laboratory can make a model of the base units. Starting with length, the meter was determined by the distance between two lines of latitude. This can be measured at any location on earth with the proper instruments. Once the length is established, a cube can be constructed that is 1/10 km on each edge. The volume of this cube is the liter. Everyone has access to water, so fill this cube with water and you have a kilogram of weight at 3.98 degrees celsius. Oh, yes, you also had to develop a thermometer by dividing the difference between water's freezing and boiling points into 100 equal parts. Decimal multiples The metric system is decimal. The next larger unit is always 10 times as large, the next smaller always 1/10 as large. You don't have to remember 12 inches to a foot, 3 feet to a yard, are there four pints in a quart or only two, etc. To convert, simply move the decimal point. Prefixes All derived units use a common set of prefixes for each multiple. "Kilo" means 1000 whether it is used both for mass (kilogram) or length (kilometre). A few units such as the tonne (megagram) and quintal (100 kilograms) survive from old units but have been rounded to metric. The prefixes which come from the Greek language (kilo, mega, giga) are multipliers and those with Latin origins (centi, milli) are divisors.

Answer 2

The metric system is based on multiples of 10, making it more logical and easier to use for calculations and conversions. It is widely used around the world, promoting consistency and simplifying communication in scientific and international contexts. Additionally, the metric system is simpler to learn and teach compared to the English system, which is more complex and less standardized.

Answer 3

There are several advantages. Some of them are:

1. They are internationally agreed as standard. Not like a gallon which can mean one amount in the US and different amount in the UK.

2. Orders of magnitude for measuring the same attribute are related by simple multiples or fractions of powers of ten conversions and only a handful of prefices are required (although there are a lot more available for very big and very small amounts). By way of contrast, the Imperial system uses:

• 2 pints in a quart

• 3 feet in a yard

• 4 quarts in a gallon

• 6 feet in a fathom

• 8 furlongs in a mile

• 9 square feet in a square yard

• 12 inches in a foot

• 14 pounds in a stone

• 16 ounces in a pound

and so on, and on and on. The decimal structure also makes it simple to use scientific notation for very small and very large quantities.

3. There are many simple relations between measures for one characteristic to another. For example, the force required to accelerate a mass of 1 kilogram by 1 metre/second^2 is 1 Newton. The pressure exerted by 1 Newton over an area of 1 Square metre is 1 Pascal.

Answer 4

Because the entire system has a base of 10, that makes it very easy to convert between different metric units.

Answer 5

The metric system and English system are two "competing" systems of units of measure.

The US is one of the few places on earth where the English system is still winning.

Answer 6

We think its easier.
