To convert one unit of measure to another, you need conversion factors. These are ratios that relate units. For example, there are 12 inches in 1 foot. So the conversion factor between inches and feet is 12 inches/1 foot.

Using conversion factors is pretty straightforward. Say you want to convert 5 feet to inches. Here are the steps:

  1. Write down the unit you have, feet (ft)
  2. Write down the unit you want, inches (in)
  3. Write the conversion factor between the two units: 12 in/1 ft
  4. Multiply the number of feet by the conversion factor: 5 ft x 12 in/1 ft = 60 in

So 5 ft = 60 in. See how we multiplied the feet by the conversion factor to get inches? The units also multiplied, but the feet unit canceled out, leaving us with just inches.

Some useful conversion factors:

•1 ft = 12 in

•1 m = 100 cm

•1 kg = 1000 g

•1 L = 1000 mL

•1 mile = 5280 ft

The key to using conversion factors successfully is making sure the units cancel out properly. Set up your problem, write the conversion factor so the units you have cancel out, and you’ll end up with the units you want. With regular practice, converting units can become second nature!

Common Conversion Factors Used in Science

When doing chemistry experiments, you’ll rely on conversion factors to calculate various measurements. Here are some of the most common ones used in science:


Kilograms (kg) and grams (g) are used to measure mass. There are 1000 g in 1 kg. For example, if you have 5 kg of a substance, that’s equal to 5000 g.


Meters (m), centimeters (cm), and millimeters (mm) measure length. There are 100 cm in 1 m and 1000 mm in 1 m. So 150 cm is equal to 1.5 m.


Liters (L) and milliliters (mL) indicate volume. There are 1000 mL in 1 L. For instance, 2.5 L is the same as 2500 mL.

Molar Mass

Molar mass relates mass in grams to moles, a unit of amount of substance. The molar mass of water is 18.015 g/mol. That means 1 mole of water has a mass of 18.015 g. Knowing molar masses allows you to convert between mass, moles and number of particles of a substance.

Using these common conversion factors, you can calculate densities, concentrations, yields, and more. Practice working through examples by hand and you’ll get the hang of problem-solving in the lab in no time!

Whether you’re a seasoned scientist or just getting started, mastering conversion factors and unit analysis is essential for success in the lab. Take your time, check your work, and don’t be afraid to ask questions. You’ve got this!

Conversion factors are ratios that relate equivalent measurements. They allow you to convert from one unit to another. For example, there are 12 inches in 1 foot. So the conversion factor between inches and feet is 12 inches/1 foot.

Some other useful conversion factors to know:

  • 1 mile = 5280 feet
  • 1 kg = 2.2 lbs
  • 1 L = 1000 mL

How to Apply Conversion Factors

To apply a conversion factor, you need to set up a ratio with the units you want to convert from on one side, and the units you want to convert to on the other side. Then, multiply the original quantity by the conversion factor ratio to get the new quantity in the desired units.

For example, to convert 50 miles to feet, you would set up the following ratio:

50 miles x (5280 feet/1 mile) = 264,000 feet

So 50 miles = 264,000 feet.

To go from feet to miles, you would flip the ratio:

264,000 feet x (1 mile/5280 feet) = 50 miles

Using conversion factors allows you to solve many types of problems where different units are involved. The key is identifying the right conversion factors, setting up the ratios properly, and multiplying correctly. With practice, using conversion factors will become second nature and allow you to convert quickly between all types of imperial and metric units.

Examining the Lab 2 Report Sheet

The Lab 2 Report Sheet provides an overview of the conversion factors you calculated and used to solve various problems. Looking it over will help reinforce what you learned.


You calculated the density of different objects like blocks of aluminum, brass and wood. Density equals mass divided by volume (D=m/v). The denser an object is, the more mass it has for its size. The density of metals is usually greater than nonmetals.

Unit Conversion

You converted units within the metric system like kilometers to meters, and grams to kilograms. You also converted between metric and customary units like inches to centimeters or pounds to kilograms. Using conversion factors, you determined how many of one unit equals another unit. For example, 2.54 cm = 1 inch.

Percent Composition

You calculated the percent composition of elements in compounds like water (H2O) and sodium chloride (NaCl). Percent composition shows what percent of the total mass of a compound is made up of each element. For water, 11.19% is hydrogen and 88.81% is oxygen by mass.

Molar Mass

You calculated the molar mass of substances by adding up the atomic masses of each element. One mole of any substance contains 6.02 x 10^23 particles (atoms or molecules). So the molar mass of water (H2O) is 18.02 grams/mole. This means one mole of water molecules has a mass of 18.02 grams.

Going over your Lab 2 Report Sheet again will reinforce how to do these types of calculations and conversions. Let your instructor know if you have any other questions! Applying what you’ve learned to solve practice problems is one of the best ways to truly understand these concepts.

Have some other questions about your Paraiso Verde plant? We’ve got you covered.

How often should I repot my Paraiso Verde?

Repotting keeps your plant healthy by providing fresh soil and a larger pot for growth. As a general rule, move your Paraiso Verde up one size every 2-3 years in the spring. Make sure the new pot has drainage holes and use a well-draining potting mix.

What are the signs my plant needs repotting?

A few signs it’s time for a move to a bigger pot:

  • Roots are protruding from the drainage holes.
  • Water runs right through the pot.
  • Plant is top heavy or tipping over.
  • Growth has slowed.

What kind of pot should I use?

Choose an attractive pot with drainage holes that is one size larger than your current pot. A pot that is too large can hold too much moisture and lead to root rot. For indoor plants, a pot with a saucer to catch excess water is ideal. Terra cotta pots are also a great choice as they breathe well.

What kind of soil should I use?

A well-draining potting mix is best for Paraiso Verde. Look for a mix formulated for houseplants or tropical plants. You can also make your own using 3 parts peat moss or coir, 2 parts perlite, and 1 part compost or worm castings. This provides the right balance of moisture retention, drainage, and nutrients for your plant.

Can I propagate new plants?

Yes, Paraiso Verde can easily be propagated from stem cuttings. Take a 6-8 inch cutting from a mature stem and remove the lower leaves. Dip in rooting hormone (optional) and place in well-draining rooting medium such as perlite or a mixture of peat and perlite. Keep the medium moist and place in a warm spot with indirect light. Roots should form in 1 to 2 months.


So there you have it, a deep dive into the conversions and formulas that make the world go round. Now you’re equipped with the know-how to tackle all kinds of real-world problems, from calculating the density of an unknown liquid to converting between Celsius and Fahrenheit.

While the concepts may seem tricky at first, with regular practice converting units and applying factors will become second nature. The key is to not get overwhelmed by all the rules and exceptions, just focus on one step at a time.

Start with the units you want to end up with, then work your way back to the original measurement using the factors that link them together. Before you know it, you’ll be solving conversion puzzles quicker than a calculator. The possibilities are endless once you master this useful life skill.
