The Guide to Essential Oil Measurements: How Many Drops in a Milliliter? Jun 18 , 2024

Whether you are creating aromatic blends for aromatherapy, concocting your own skincare products, or simply enhancing your space with a diffuser, precise measurements are essential to achieving the desired results and ensuring safety. Inaccurate measurements can result in ineffective or potentially harmful blends, particularly when dealing with potent essential oils. Therefore, understanding how to accurately measure essential oils is crucial for anyone using them. This article will provide comprehensive guidance on this topic.

Factors Affecting Droplet Size

Viscosity: The density of a liquid impacts the formation of droplets. Thicker liquids, such as honey or certain essential oils, produce larger droplets compared to thinner liquids like water, which yield more droplets per milliliter.

Dropper Size: The design and size of the dropper's opening play a significant role in droplet size. A larger opening results in larger droplets, while a smaller opening produces smaller ones.

Temperature: The temperature of the liquid also affects droplet size. Hotter liquids are less viscous, creating smaller droplets with increased drop size, while colder liquids, being more viscous, form larger droplets. 

How Many Drops of Essential Oil are in a Milliliter?

Typically, there are around 20 drops of essential oil in each milliliter. However, this can vary based on factors such as the type of oil and the dropper design. It's important to note that this average serves only as a guideline, and the specific properties of the oil being used should always be considered.

Below are examples of drop sizes for different oils:

- Lavender oil: approximately 20 drops per milliliter

- Peppermint oil: approximately 22 drops per milliliter

- Frankincense oil: approximately 18 drops per milliliter

- Patchouli oil: approximately 15 drops per milliliter

Tips for Consistent Measurements

Utilize Precision Droppers: Our finalized oil bottles come equipped with calibrated droppers to ensure consistent drop sizes, thereby enhancing measurement accuracy.

Work in a Controlled Environment: Avoid measuring oils in areas with extreme temperatures or humidity, as these factors can affect viscosity and droplet size. Embrace Consistency: Always employ the same tools and methods when measuring to maintain uniformity in your blends.

Frequently Asked Questions

Can I use a standard dropper for all essential oils?

Using a standard dropper for all essential oils may seem convenient, but it may not always provide the accuracy you need. This is because since standard droppers vary greatly in design and dropper size and essential oils have different viscosities, standard droppers may not be able to account for these differences, resulting in inconsistent measurements.

What should I do if I don't have a dropper?

If you find yourself without a dropper, there are still ways to measure essential oils accurately. Here are some alternatives:

Use a pipette: A pipette can be a good substitute for a dropper. It allows you to accurately measure small volumes of liquid. Make sure the pipette is clean and calibrated for best results.

Measuring spoons: You can use measuring spoons for large volumes. Note that one teaspoon usually equals about 100 drops of essential oil, but this can vary depending on the viscosity of the oil.

Syringe: A small syringe can also be used for measuring, which provides precise control over the amount of oil dispensed.

How can I ensure consistent measurements every time?

Consistency is key when using essential oils. You need to use precision tools, work in a controlled environment, follow standard procedures, calibrate your tools regularly, keep records, and these tips can help you achieve consistent measurements every time.
