Measuring Length - Customary Units
Use a inch leader to meacertain the size of real civilization objects to the nearemainder inch and also fifty percent inch.
You are watching: What is another name for the metric system
The metric system is a device of measurement that uses the meter, liter, and also gram as base units of length (distance), capacity (volume), and weight (mass) respectively.
The offered figure mirrors the setup of the metric units, which are smaller sized or bigger than the base unit.The systems to the ideal of the base unit are smaller sized than the base unit. As we move to the best, each unit is 10 times smaller sized or one-tenth of the unit to its left. So, a ‘deci’ suggests one-tenth of the base unit, ‘centi’ is one-tenth of ‘deci’ or one-hundredth of the base unit and also ‘milli’ is one-tenth of ‘centi’ or one-thousandth of the base unit.The units to the left of the base unit are bigger than the base unit. As we move to the left, each unit is 10 times higher than the unit to its right. So, a ‘deca’ implies ten times of the base unit, ‘hecto’ is ten times of ‘deca’ or hundred times of the base unit and also ‘killo’ is ten times of ‘hecto’ or thousand also times of the base unit.
So, the devices for length, weight (mass) and also capacity(volume) in the metric system are:
Length: Millimeter (mm), Decimeter (dm), Centimeter (cm), Meter (m), and Kilometer (km) are supplied to measure exactly how lengthy or wide or tall an item is.
Examples include measuring the thickness or length of debit card, length of fabric, or distance in between two cities.
Weight: Gram (g) and also Kilogram(kg) are supplied to measure just how hefty an object, utilizing instruments.
Instances encompass measuring weight of fruits or, our own body weight.
Capacity: Milliliter (ml) and Liter (l) are provided to meacertain just how a lot amount of liquid an item deserve to host.
Examples incorporate measuring the amount of juice in a juice can, or amount of water of in a water tank.
Time:2nd is the base unit for time. The other metric systems of time are:
Metric Conversions:Meters, grams and also liters are taken into consideration the base systems of length, weight and also volume, respectively.
Here’s how we have the right to multiply or divide for making metric conversions. To transform a bigger unit to the smaller sized unit, we relocate left to create, we multiple by 10. Moving right to left, from smaller sized unit to bigger, we divide by 10.
Let us look at some examples of converting from one unit to an additional.
Example 1: Convert 5 km to m.
As 1 kilometres = 1000 m
As such, 5 kilometres = 5 × 1000 = 5000 m
Example 2: Convert 250 kg to milligrams.
We understand, 1 g = 1000 mg and 1 kg = 1000 g
So, we first convert the kg to g as:
1 kg = 1000 g
Thus, 250 kg = 250 × 1000 g = 250,000 g
Now, converting g to mg:
1 g = 1000 mg, therefore: 250,000 g = 250,000 × 1000 mg = 250,000,000 mg
Example 3: Convert 250 ml to liters.
1 liter = 1000 ml
Thus, 450 ml = 450 ÷ 1000 = 0.45 liter
The US Standard Units or the Customary System supplies customary systems.
This system measures:Length or distance in inches, feet, yards, and also miles.Capacity or volume in fluid ounces, cups, pints, quarts or gallons.Weight or mass in ounces, pounds and tons.
A tonne is 1,000 kilograms.
The metric system has actually its beginnings ago 1670 by a mathematician referred to as Gabriel Mouton.
Due to the fact that the 1960s the metric device is referred to as the "International System of Units" or "SI" (from the French "Système International").
The prefixes of the metric system deserve to be remembered utilizing the mnemonic “King Henry Died of Drinking Cold Milk”
There are units better than the kilo too. These have actually predeal with mega, giga and tera. A mega is 1000 times of kilo. A giga is 1000 times of mega and also a tera is 1000 times of a giga.
