### How to Convert Length Units using a Conversion Factor

For example, to convert between ft and m,

conversion factor is 1 ft = approx 0.305 m

To convert feet to meters, multiply by 0.305:

ft x 0.305 = m

3 ft x 0.305 = 0.914 m

To convert meters to feet, divide by 0.305:

m / 0.305 = ft

3 m / 0.305 = 9.84 ft

### Convert Weight Units using a Conversion Factor

For example, to convert between lb and kg,

conversion factor is 1 lb = approx 0.454 kg

To convert pounds to kilograms, multiply by 0.454:

lb x 0.454 = kg

3 lb x 0.454 = 1.36 kg

To convert kg to lb, divide by 0.454:

kg / 0.454 = lb

3 kg / 0.454 = 6.61 lb

### Convert Volume Units using a Conversion Factor

For example, to convert between quarts and liters,

conversion factor is 1 qt = approx 0.946 l

To convert quarts to liters, multiply by 0.946:

qt x 0.946 = l

3 qt x 0.946 = 2.84 l

To convert l to qt, divide by 0.946:

l / 0.946 = qt

3 l / 0.946 = 3.17 qt

### Learn how to convert temperatures

Formula for conversion from celsius to fahrenheit:

°F = ((9/5) x °C) + 32

Formula for conversion from fahrenheit to celsius:

°C = (5/9) x (°F-32)

What is 80 °F in °C?

°C = (5/9) x (80-32) = (0.556) * (48) = 26.7 °C

What is -40 °C in °F?

°F = ((9/5) x -40) + 32 = (-72) + 32 = -40 °F

so, -40 °C = -40 °F, an interesting coincidence!
