Question 1

How do you convert Celsius to Fahrenheit?

Accepted Answer

The formula is: °F = (°C × 9/5) + 32. Key benchmarks: 0°C = 32°F (freezing), 20°C = 68°F (comfortable), 37°C = 98.6°F (body temp), 100°C = 212°F (boiling). Quick mental trick: double the Celsius value, subtract 10%, then add 32. Example: 25°C → 50, minus 5 = 45, plus 32 = 77°F.

Question 2

How many kilograms are in a pound?

Accepted Answer

1 lb = 0.4536 kg. 1 kg = 2.2046 lbs. Common references: 100 lbs = 45.4 kg; 150 lbs = 68 kg; 200 lbs = 90.7 kg; 1 kg = 2.2 lbs. Canada officially uses kilograms but many Canadians still think in pounds for body weight.

Question 3

How many kilometres are in a mile?

Accepted Answer

1 mile = 1.609 km. 1 km = 0.621 miles. Common conversions: 5 km = 3.1 mi; 10 km = 6.2 mi; 100 km/h = 62.1 mph; 60 mph = 96.6 km/h. Speed limit comparison: Canada's highway limit of 100 km/h equals about 62 mph in the US.

Question 4

How many litres are in a US gallon?

Accepted Answer

1 US gallon = 3.785 L. 1 Imperial gallon (used in the UK and historically in Canada) = 4.546 L. Canada sells fuel in litres, so if you're used to US gallons, multiply the litre price by 3.785 to compare. 1 L = 0.264 US gal = 0.220 Imperial gal.

Question 5

What is the difference between weight and mass?

Accepted Answer

Mass is a measure of matter (kilograms, pounds) and is constant everywhere. Weight is the gravitational force on that mass (Newtons) and varies by location — you'd weigh less on the moon but your mass stays the same. In everyday Canadian life, 'weight' and 'mass' are used interchangeably. Bathroom scales measure force and convert it to kg assuming standard gravity.
