# Measurements

The act of telling the size, length, weight, etc, of something, is called measurement which is all about numbers and fractions.

## What Do We Mean by Measurements?

Anytime we use a process to find out the size, length, or amount of something, we’re measuring. We measure things including weight, time, length, and many other measurable things.

## System of Measurement

A system of measurement is a collection of units of measurement and rules relating them to each other.

### System of Measurement: Types

We have two types of systems of measurement:

• The Metric System
• The Imperial System

### The Metric System

The Metric System, adopted in France in 1795, is a system of measurement that is now used officially in almost all countries. After the French Revolution, the government decided to have one standard system of measurement to unify the whole country. Since then, 'The Metric System', also called SI, has been the universal measurement system for nearly all countries except the USA.

### The Imperial System

The Imperial System of Units (also called imperial system or imperial units or British Imperial) was a system of measurement that was mainly used by countries like the UK, Canada, New Zealand, Australia, USA, etc. However, the only country that currently uses this system for measurement is the USA. It is based on feet, inches, pounds, and Fahrenheit.

## Volume

All three-dimensional objects occupy a space, we measure this space using units of 'volume'. Volume is the space occupied by an object in three-dimensional space. It is used to measure solids and liquids.

abbreviation equivalents of the same system(imperial) metric equivalent
cubic yard cu yd 27 cubic feet, or 46,656 cubic inches 0.765 cubic metre
cubic foot cu ft 1,728 cubic inches, or 0.0370 cubic yard 0.028 cubic metre
cubic inch cu in 0.00058 cubic foot, or 0.000021 cubic yard 16.387 cubic centimetres
acre-foot ac ft 43,560 cubic feet, or 1,613 cubic yards 1,233 cubic metres
board foot bd ft 144 cubic inches, or 1/12 cubic foot 2.36 litres
cord cd 128 cubic feet 3.62 cubic metres

## Weight

Weight measures the heaviness of objects, which can be food, a ball, human weight, etc. Let's see which units are used to measure weight in the imperial (US) and metric systems.

abbreviation equivalents of the same system(imperial) metric equivalent
ton 20 hundredweight, or 2,240 pounds 1.016 metric tons
hundredweight cwt 100 pounds, or 0.05 ton 45.359 kilograms
pound lb 16 ounces, or 7,000 grains 0.454 kilogram
ounce oz 16 drams, 437.5 grains, or 0.0625 pound 28.350 grams
dram dr 27.344 grains, or 0.0625 ounce 1.772 grams
grain gr 0.037 dram, or 0.002286 ounce 0.0648 gram
stone st 0.14 hundredweight, or 14 pounds 6.35 kilograms

## Area

The area of an object can be measured from several aspects. Length typically refers to the longest side or the distance between two points. Width refers to the horizontal dimension, while height refers to the vertical dimension. Finally, depth is the distance from the surface to the farthest point.
In the Imperial System, measurements of area are typically expressed in units such as inches, feet, miles, and acres.

• Area
abbreviation equivalents of the same system(imperial) metric equivalent
square mile sq mi 640 acres, or 102,400 square rods 2.590 square kilometres
acre -- 4,840 square yards, or 43,560 square feet 0.405 hectare, or 4,047 square metres
square rod sq rd 30.25 square yards, or 0.00625 acre 25.293 square metres
square yard sq yd 1,296 square inches, or 9 square feet 0.836 square metre
square foot sq ft 144 square inches, or 0.111 square yard 0.093 square metre
square inch sq in 0.0069 square foot, or 0.00077 square yard 6.452 square centimetres
• Length
abbreviation equivalents of the same system(imperial) metric equivalent
nautical mile nmi 6,076 feet, or 1.151 miles 1,852 metres
mile mi 5,280 feet, 1,760 yards, or 320 rods 1,609 metres, or 1.609 kilometres
furlong fur 660 feet, 220 yards, or 1/8 mile 201 metres
rod rd 5.50 yards, or 16.5 feet 5.029 metres
fathom fth 6 feet, or 72 inches 1.829 metres
yard yd 3 feet, or 36 inches 0.9144 metre
foot ft 12 inches, or 0.333 yard 30.48 centimetres
inch in 0.083 foot, or 0.028 yard 2.54 centimetres

## Temperature

When we want to talk about temperature, we must know that there are differences between they way the world analyzes it and the way Americans do it. We mainly use Celsius whereas, Fahrenheit is used among Americans. The difference between them is that the Celsius scale, or Centigrade scale, is based on water freezing at 0°C and boiling at 100°C. On the Fahrenheit scale, however, water freezes at 32°F and boils at 212°F. Look at the formula below:

• 1 Celsius = 33.80 Fahrenheit

By using the formula above, we can easily convert Celsius degrees to Fahrenheit.

## Cooking measurments

When cooking, you might face different measurement units. Let's go through some of them:

• Converting gallons, quarts, pints, cups, ounces, tablespoons and teaspoons.
1 gallon 4 quarts, 8 pints, 16 cups, 128 ounces and 3.8 liters
1 quart 2 pints, 4 cups, 32 ounces and 950 ml
1 pint 2 cups, 16 ounces and 480 ml
1 cup 16 tablespoons, 8 ounces and 240 ml
1 ounce 2 tablespoons and 30 ml
1 tablespoon 3 teaspoons, 1/2 ounce and 15 ml
1 teaspoon 5 ml

### Expressions for measuring

There are some expressions you might face in the cooking books, here we have explained some of them:

• Lightly packed
• Firmly packed
• Even / level
• Heaping / heaped
• Rounded

### Lightly packed

The ingredient is pushed lightly into the measuring device, only tightly enough to make sure no air pockets.

### Firmly packed

With a spoon, or by hand, the ingredient is pushed as tightly as possible into the measuring device.

### Even / level

A precise measure of an ingredient, get rid of all of the ingredients that rise above the rim of the measuring device. Sweeping across the top of the measure using the back of a knife or something like that is a common leveling method.

### Heaping / heaped

The highest amount of an ingredient that will stay on the measuring device.

### Rounded

Letting a measure of an ingredient accumulate above the rim of the measuring device by itself, into a soft, rounded shape.
