RSO Oil Dosage Calculator: How Many ml Should You Take?
To calculate your RSO dose in ml, divide the desired mg of THC by the mg per ml of your oil. Start with a grain-of-rice size (about 0.01 ml) and adjust based on tolerance.
RSO Oil Dosage Calculator: Convert mg to ml for Your Perfect Dose
To find your RSO dose in ml, first check your oil's Certificate of Analysis (COA) for the THC and CBD content in mg/g. Then use the formula: (THC% + CBD%) × 10 = mg of cannabinoids per 1 g of oil. Since 1 g of RSO is roughly 1 ml, this gives you mg/ml. Divide your target dose (in mg) by the mg/ml to get ml.
| Step | Action | Example |
|---|---|---|
| 1. Find potency | Look at COA: THC% and CBD% | 70% THC + 2% CBD = 72% total |
| 2. Calculate mg/ml | Multiply total % by 10 | 72 × 10 = 720 mg per 1 g (≈1 ml) |
| 3. Choose target dose | Start low (e.g., 2.5 mg) for beginners | 2.5 mg desired |
| 4. Divide to get ml | Target mg ÷ mg/ml | 2.5 ÷ 720 ≈ 0.0035 ml |
| 5. Measure with syringe | Use 1 ml syringe with 0.01 ml markings | Draw 0.0035 ml (tiny, about half a grain of rice) |

Edible Dosage Calculator: How Much RSO (ml) to Add to Your Recipe
When infusing RSO into edibles like brownies or coconut oil, calculate the ml per serving by dividing total mg of THC in your batch by the number of servings. Start with the same formula: (THC% + CBD%) × 10 = mg/ml. Multiply by the ml of RSO you add, then divide by servings.
| Batch size | RSO added (ml) | Total mg THC | Servings | mg per serving |
|---|---|---|---|---|
| 1 cup coconut oil | 1 ml (720 mg/ml) | 720 mg | 16 | 45 mg |
| 1 batch brownies | 0.5 ml (720 mg/ml) | 360 mg | 12 | 30 mg |
| 1 batch gummies | 0.25 ml (720 mg/ml) | 180 mg | 24 | 7.5 mg |
| 1 stick butter | 0.75 ml (720 mg/ml) | 540 mg | 32 | 16.9 mg |
Always mix RSO thoroughly into warm fat (like coconut oil or butter) for even distribution. Use our edible dosage calculator during your free consultation to get exact numbers for your recipe.
RSO Consumption Methods: Which One Gives You the Most Precise Dose?
For precise dosing in ml, the best methods are those that allow direct measurement with a syringe. Here's a comparison of common RSO consumption methods:
| Method | Precision | Onset | Best for |
|---|---|---|---|
| Sublingual (under tongue) | High – use syringe to measure ml | 15–30 minutes | Quick absorption, easy to adjust |
| Oral tincture | High – use dropper or syringe | 30–90 minutes | Consistent dosing, longer duration |
| Edibles (infused) | Moderate – depends on mixing | 45–120 minutes | Discreet, longer effects |
| Nasal spray | High – per spray dose | 5–15 minutes | Fast onset, precise per spray |
| Rectal syringe | Very high – syringe measurement | 10–30 minutes | High bioavailability, avoids digestion |
Our team can help you choose the best method based on your needs. We offer RSO as pure oil, tincture, nasal spray, and rectal syringe—all with clear ml markings.
RSO Dosage for Beginners: How Many ml Is a Grain-of-Rice Dose?
For beginners, the safest starting dose is about the size of a grain of rice. In ml, this is roughly 0.01 ml of RSO, assuming a potency around 700–800 mg/ml. Always start low and go slow.
| Dose reference | Approximate ml | Approximate mg THC (at 720 mg/ml) |
|---|---|---|
| Grain of rice | 0.01 ml | 7.2 mg |
| Half grain of rice | 0.005 ml | 3.6 mg |
| Pea-sized | 0.05 ml | 36 mg |
| Standard beginner dose | 0.01–0.02 ml | 7–14 mg |
Wait at least 2 hours before taking more. Our free consultation includes a personalized dosing schedule to help you find your ideal ml dose safely.
Tetrahydrocannabinol
Tetrahydrocannabinol (THC) is a cannabinoid found in cannabis. It is the principal psychoactive constituent of Cannabis and one of at least 113 total cannabinoids identified on the plant. Although the chemical formula for THC (C21H30O2) describes multiple isomers, the term THC usually refers to the delta-9-THC isomer with chemical name (−)-trans-Δ9-tetrahydrocannabinol. THC, also known pharmaceutically as dronabinol, is used medically to relieve chemotherapy-induced nausea and HIV/AIDS-related anorexia. Nabiximols, a botanical drug which contains THC, is used medically to treat symptoms of multiple sclerosis, including spasticity and neuropathic pain. THC acts as a partial agonist at CB1 and CB2 cannabinoid receptors. THC can be administered orally, inhaled, or transdermally, with bioavailability and onset varying by route, and is extensively metabolized in the liver to active and inactive metabolites before being excreted in feces and urine. Side effects include red eyes, dry mouth, drowsiness, memory impairment, anxiety, and, with chronic use, cannabinoid hyperemesis syndrome. While human overdose is rare, THC can interact with other drugs and has a complex pharmacokinetic profile. Understanding THC potency in mg per ml is essential for calculating your RSO dose accurately.
Understanding RSO Potency: How to Estimate mg of THC per ml
RSO potency varies by batch, but most quality oils contain 60–80% THC and 1–5% CBD. To estimate mg per ml, use the formula: (THC% + CBD%) × 10 = mg/ml. For example, 70% THC + 2% CBD = 720 mg/ml.
| THC % | CBD % | Total cannabinoid % | mg per ml (approx) |
|---|---|---|---|
| 60% | 2% | 62% | 620 mg/ml |
| 70% | 2% | 72% | 720 mg/ml |
| 75% | 3% | 78% | 780 mg/ml |
| 80% | 1% | 81% | 810 mg/ml |
Our RSO comes with a COA for every batch, so you can calculate your exact mg/ml. We use only cannabis flower (no trim) for consistent potency.

Frequently asked questions
How many ml is a grain of rice size RSO dose?
A grain-of-rice dose is approximately 0.01 ml of RSO, which equals about 7–8 mg of THC at typical potency (720 mg/ml). This is a safe starting point for beginners.
Can I use a regular dropper to measure RSO in ml?
A syringe is more accurate than a dropper for measuring RSO in ml. Droppers vary in drop size, while syringes have precise 0.01 ml markings for consistent dosing.
What if my RSO doesn't have a COA?
Without a COA, you cannot know the exact mg/ml. We recommend only using lab-tested RSO from a trusted source. Our products include a COA for every batch.
How do I adjust my RSO dose in ml over time?
Increase your dose gradually by 0.005–0.01 ml (about half a grain of rice) every few days as your tolerance builds. Our team can help you create a titration schedule.
