1. Intro to Physics Units

A passenger jet uses about 12 liters of fuel per km of flight. What is that value expressed as miles per gallon?

If a distance is $\mathrm{10,000}m$, approximately how many miles is this distance?

The speed of light is approximately 3.00×10⁸ m/s. Convert this speed to yards/week (yd/wk).

A square field measuring 100.0 m by 100.0 m has an area of 1.00 hectare. An acre has an area of 43,600 ft². If a lot has an area of 12.0 acres, what is its area in hectares?

The temperature outside is $40°C$. What is this in $°F$?

A certain fuel-efficient hybrid car gets gasoline mileage of 55.0 mpg (miles per gallon). If you are driving this car in Europe and want to compare its mileage with that of other European cars, express this mileage in km/L (L = liter).

Convert the following to basic SI units or a combination of basic SI units:

62 ft/day

Using the approximate conversion factors in Table 1.5, convert the following SI units to English units without using your calculator.

25 m/s

The density of gold is 19.3 g/cm³. What is this value in kilograms per cubic meter?

A car is traveling at a velocity of $58\frac{m}{s}$. What is this velocity in $miles$ per $hour$ ($mph$)?

Computer chips (Fig. 1–15) can be etched on circular silicon wafers of thickness 0.300 mm that are sliced from a solid cylindrical silicon crystal of length 25 cm. If each wafer can hold 750 chips, what is the maximum number of chips that can be produced from one entire cylinder?

While driving in an exotic foreign land, you see a speed limit sign that reads 180,000 furlongs per fortnight. How many miles per hour is this?

An intravenous saline drip has 9.0 g of sodium chloride per liter of water. By definition, 1 mL = 1 cm³. Express the salt concentration in kg/m³.

American football uses a field that is 100.0 yd long, whereas a soccer field is 100.0 m long. Which field is longer, and by how much (give yards, meters, and percent)?

Determine the conversion factor between km/h and m/s.
