Unit Conversion Example Problems

Unit conversion problems constitute the first week of nearly every science course. Measurement is a basic skill in science, but not all measurement methods are the same. People measure the same thing in different ways and use different units. To communicate between scientists, there has to be a method of converting between the different measurement units.

This is a collection of unit conversion example problems to help you learn the general method and mindset of converting units. Most of these include an example going the opposite direction (for example: cm to m and m to cm).

General Unit Conversion Example

• How to Convert Between Units – Ladder Method

This is the way I tackle conversions between units. It outlines how to use a conversion factor to step-by-step reach the desired end units. This method is specially useful for measurements with more than one conversion like kilometers/hour to meters/sec.

Length Unit Conversion Example Problems

• Feet to Inches (ft to in) Conversion
• Inches to Centimeters (in to cm) Conversion
• Miles to Kilometers (mi to km) Conversion
• Nanometers to Angstroms (nm to Å) Conversion

Area Unit Conversion Example Problems

• Square Centimeter to Square Meter (cm² to m²) Conversion

Volume Unit Conversion Example Problems

• General Volume Example – Step by step conversion between 3 linear measurements to find the volume.
• Cubic Centimeters to Cubic Meters (cm³ to m³) Conversion
• Cubic Centimeters to Liters (cm³ to L) Conversion
• Cubic Feet to Liters (ft³ to L) Conversion
• Cubic Inches to Cubic Feet (in³ to ft³) Conversion
• Cubic Inches to Liters (in³ to L) Conversion
• Gallon to Liter (gal to L) Conversion
• Fluid Ounce to Milliliter (fl oz to mL) Conversion

Mass Unit Conversion Example Problems

• Grams to Kilograms (g to Kg) Conversion
• Pounds to Kilograms (lbs to Kg) Conversion

Temperature Unit Conversion Example Problems

• Celsius to Fahrenheit (°C to °F) Conversion
• Celsius to Kelvin (°C to K) Conversion
• Fahrenheit to Celsius (°F to °C) Conversion
• Fahrenheit to Kelvin (°F to K) Conversion
• Kelvin to Celsius (K to °C) Conversion
• When does Celsius Equal Fahrenheit?
• When does Fahrenheit Equal Kelvin?

Pressure Unit Conversion Example Problems

• Atmospheres to Kilopascals (atm to kPa) Conversion
• Atmospheres to Kilopascals (atm to kPa) Conversion
• Atmospheres to Pounds per Square Inch (atm to PSI) Conversion
• Millimeters of mercury to millibars (mmHg to mbar) Conversion
• Millimeters of mercury to kilopascals (mmHg t kPa) Conversion

Mole and Concentration Conversion Example Problems

• Grams to Moles (g to mol) Conversion
