Mass Conversion Examples

 Let's go through some common mass conversions:

Converting Grams to Kilograms:

1 kilogram=1,000 grams

For example, if you have a mass of 2,500 grams, it is equal to 2,500 grams÷1,000=2.5 kilograms

Converting Kilograms to Grams:

1 kilogram=1,000 grams

If you have a mass of 3 kilograms, it is equal to 3 kilograms×1,000=3,000 grams

Converting Ounces to Grams:

1 ounce≈28.35 grams

For example, if you have a mass of 10 ounces, it is approximately equal to 10 ounces×28.35 grams/ounce≈283.5 grams

Converting Pounds to Kilograms

1pound≈0.45359kilograms

If you have a mass of 5 pounds, it is approximately equal to 5 pounds×0.45359 kilograms/pound≈2.26795 kilograms

Converting Kilograms to Pounds:

        1 pound≈0.45359 kilograms

For example, if you have a mass of 8 kilograms, it is approximately equal to 8 kilograms÷0.45359 kilograms/pound≈17.637 pounds

Volume

Metric System

Liters (L), milliliters (mL)

Imperial System

Fluid ounces, cups, pints, quarts, gallons

Conversions

1 liter = 1,000 milliliters

1 fluid ounce ≈ 29.57 milliliters

1 cup ≈ 236.59 milliliters

1 pint = 2 cups

1 quart = 2 pints

1 gallon = 4 quarts

Volume Conversion Examples

Let's go through some common volume conversions:-

Converting Liters to Milliliters

1 liter=1,000 milliliters

For example, if you have a volume of 2.5 liters, it is equal to 2.5 liters×1,000=2,500 milliliters

Converting Milliliters to Liters

1 liter=1,000 milliliters

If you have a volume of 500 milliliters, it is equal to 500 milliliters÷1,000=0.5 liters

Converting Cups to Milliliters

1 cup≈236.59 milliliters

For example, if you have a volume of 3 cups, it is approximately equal to 3 cups×236.59 milliliters/cup≈709.77 milliliters

Converting Pints to Liters

1 pint≈0.47318 liters

If you have a volume of 2 pints, it is approximately equal to 2 pints×0.47318 liters/pint≈0.94636 liters

Converting Gallons to Liters

1 gallon≈3.78541 liters

For example, if you have a volume of 4 gallons, it is approximately equal to 4 gallons×3.78541 liters/gallon≈15.14164 liters

Temperature

Celsius (Centigrade)

Commonly used in the metric system

Fahrenheit

Commonly used in the imperial system

Conversions

To convert Celsius to Fahrenheit:  ° F= (°C×9/5) + 32

To convert Fahrenheit to Celsius: ° C = (°F−32) × 5/9

Temperature Conversion Examples

Let's go through some common temperature conversion examples between Celsius and Fahrenheit:

Converting Celsius to Fahrenheit

The formula is ° F= (°C×9/5) + 32

For example, if you have a temperature of 20 degrees Celsius, the conversion is (20×9/5) +32=68 degrees Fahrenheit.

Converting Fahrenheit to Celsius

The formula is ° C = (°F−32) × 5/9

If you have a temperature of 77 degrees Fahrenheit, the conversion is (77−32) × 5/9=25 degrees Celsius.

Converting Celsius to Fahrenheit for Boiling Point of Water

        The boiling point of water in Celsius is 100 degrees, and in Fahrenheit, it is (100×9/5) + 32 = 212 degrees Fahrenheit.

Converting Fahrenheit to Celsius for Freezing Point of Water

        The freezing point of water in Fahrenheit is 32 degrees, and in Celsius, it is (32−32) × 5/9=0 degrees Celsius.

Converting Celsius to Fahrenheit for Body Temperature

Normal body temperature is around 37 degrees Celsius, and in Fahrenheit, it is (37×9/5) + 32=98.6 degrees Fahrenheit.

Time

Seconds, minutes, hours, days, weeks, months, years

Conversions

1 minute = 60 seconds

1 hour = 60 minutes

1 day = 24 hours

1 week = 7 days

1 month can vary from 28 to 31 days

1 year = 365 days (or 366 in a leap year)

Time Conversion Examples

 Let's go through some common time conversion examples:

Converting Hours to Minutes

1 hour=60 minutes

For example, if you have duration of 3 hours, it is equal to 3 hours×60=180 minutes

Converting Minutes to Seconds

1 minute=60 seconds

If you have duration of 5 minutes, it is equal to 5 minutes×60=300 seconds.

Converting Hours to Seconds

1 hour=60 minutes×60 seconds=3,600 seconds

For example, if you have duration of 2 hours, it is equal to 2 hours×3,600=7,200 seconds.

Converting Days to Hours

1 day=24 hours

If you have duration of 4 days, it is equal to 4 days×24=96 hours.

Converting Weeks to Days

1 week=7 days

For example, if you have duration of 3 weeks, it is equal to 3 weeks×7=21 days.

 These are just some examples, and there are many other specialized measuring scales depending on the specific quantity being measured. It's important to be familiar with these conversions, especially when working with different units in various fields such as science, engineering, construction, and everyday life.
