1. Intro to Physics Units

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

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

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

Bacteria vary in size, but a diameter of 2.0 μm is not unusual. What are the volume (in cubic centimeters) and surface area (in square millimeters) of a spherical bacterium of that size?

A car is traveling at $55$ miles per hour. What is this speed approximately in $\mathrm{km}/h$?

Convert 850 ft to km.

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

How many gallons are in 1 cubic meter (m³)?

Convert $2.5m^3$ to $\operatorname{cm}^3$

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

2.2 x 10⁴ mi²

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

25 m/s

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

62 ft/day

According to the label on a bottle of salad dressing, the volume of the contents is 0.473 liter (L). Using only the conversions 1 L = 1000 cm³ and 1 in. = 2.54 cm, express this volume in cubic inches.

The RDA for the trace element selenium is 0.000070 g/day. Express this dose in mg/day.

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).
