Conversions

In certain situations, we need to convert the quantity in one scale to other as per the requirement. This process of converting measured value into other units of same type is known as Conversion.

Conversion can be done for same types of quantities. Converting one type of units to another type doesn't exist.

For Example: we can mention 1 km as 1000 meters. Here, Km and meter are of same type. They both are being used to measure the length. Likewise, we may be required to convert one scaled value to other.

Measurement Conversion

Back to Top
Before we go into word problems based on measurement conversions and conversion table, we need to know the following things:

Distance
1 inch = 2.540 centimeters
1 centimeter = 0.3937 inches
1 foot = 12 inches = 30.48 centimeters

1 mile = 1.609 kilometers
1 kilometer = 0.6214 miles

1 meter = 100 centimeters
1 meter = 1000 meters

Speed
1 Kilometer per hour = 0.62 Miles per hour
1 Mile per hour = 1.609 Kilometer per hour

Area
1 square meter = 10.76 feet squares
1 square foot = 929 centimeters squares

1 acre = 43.560 feet squares
1 Square mile = 640 acres

Capacity
1 US Gallon = 3.785 liters
1 British Gallon = 1.201 US gallon

Temperature
32 Degrees Fahrenheit = 0 Degrees Celsius (Freezing Point)

Weight
1 Pound = 0.453 Kilogram
16 ounces, 453 grams
1 Ounce = 28 grams
1 Kilogram = 2.2 pounds
1 Kilogram = 1000 grams

Unit Conversion

Back to Top
Unit conversion function is used to convert the given set of values in terms such as a weight, temperature, length, height, area, volume, width etc.
The units of the above functions are meters, cubic meters, feet, inches, millimeters, Celsius, Fahrenheit, pounds, centimeters etc.

Example for Unit Conversion


To convert 1000 acres to Hectares.

Solution: Here we have to convert acres to Hectares.

1 acres = 0.404685642 hectares

Therefore,

1000 acres = 0.404685642 hectares x 1000 acres

= 404.685642

The answers for 1000 acres are equal to 404.685642 Hectares.

Metric Conversions

Back to Top
The conversion is mainly done between the measurements. Generally, there are two types of measurements like standard measurement and metric measurements. There are more measurements in metric.
The metric measurements used to measure the area, distance, energy, force, mass, power, pressure, velocity or speed, volume or capacity and volume of liquid.
The metric conversion chart is given below. The basic metric units are meter, gram and litre. Some prefixes are given here for weight measures.

1000 grams = 1 kilogram

100 grams = 1 Hectogram

10 grams = 1 dekagram

0.1 grams = 1 decigram

0.01 grams = 1 centigram

0.001 grams = 1 milligram

Below you could see metric conversions for,
  • Length conversion
  • Weight conversion
  • Volume conversion
  • Area conversion
  • Speed conversion
