Frequently Asked Questions (FAQ)
For beginners, 5–10mg THC per serving is generally safe. Regular users might prefer 15–25mg. Always start low and wait 1–2 hours before taking more. Our calculator helps you dial in the right dosage based on your recipe and infused butter.
Yes. Raw cannabis contains THCA, which is not psychoactive. Decarboxylation turns THCA into THC. Skipping this step will result in weak or inactive edibles.
Absolutely. Coconut oil is high in saturated fat, making it ideal for cannabinoid absorption. It's also vegan-friendly. Select "Coconut Oil" as your solvent to adjust density and potency.
Edibles typically take 30–90 minutes, with full effects lasting 4–8 hours. Start with one serving and wait at least 2 hours before increasing.
Yes. This is a full THC + CBD calculator. Enter your CBD percentage alongside THC, and use the Results CBD tab to see separate total and per-serving CBD estimates alongside THC.
Yes. Enter CBD percentage and use the Results CBD tab to see totals and per‑serving estimates.
Common home method: 115°C / 240°F for ~40 minutes. Use an oven thermometer; avoid scorching to preserve terpenes.
Refrigerate in an airtight container for 1–2 weeks; freeze for longer storage. Keep away from light and heat.
Yes. We apply decarb and infusion efficiency from config.json (oven decarb 75%, butter infusion 93%) so servings stay conservative. Lab kinetics often show higher conversion—see the decarb calculator and our notes on scientific edibles calculator alternatives.
Cannabutter Ratio Calculator: Accurate Dosing Starts Here
Understanding your cannabutter ratio is the key to creating consistent, effective, and safe cannabis edibles. Whether you’re infusing butter, oil, or coconut fat, this ratio tells you how much THC (or CBD) you’re delivering per gram—or per cookie.
What is a Cannabutter Ratio?
The cannabutter ratio is the relationship between the amount of cannabis used and the total fat in your infusion. This ratio helps you calculate how many milligrams of THC (or CBD) end up in each gram or ounce of your butter or oil.
Example:
- 5 grams (0.18 oz) of cannabis at 20% THC = 1,000mg total THC inside your bud
- Decarbed in oven: ~75% efficiency = 750mg active THC
- Infused into 1 cup (227g or 8 oz) of butter
- = ~3.3mg THC per gram of butter (or ~94mg per oz)
Use Our Calculator
Our edible dosage calculator lets you choose your cannabis strength, infusion method, and butter amount in both metric and imperial units. No math required.
It also adjusts for infusion loss, decarboxylation efficiency, and lets you see how strong your final recipe will be—per portion.

- Butter used in recipe: 150g (5.3 oz / ~⅔ cup) → includes ~25g regular butter
- 16 servings: ~20mg per cookie
Ingredients (Metric & Imperial)
- 250g all-purpose flour (2 cups)
- 150g soft cannabutter (5.3 oz / ~⅔ cup)
- 200g dark chocolate chips (7 oz / 1¼ cups)

- 90g brown sugar (3.2 oz / ~½ cup packed)
- 90g white sugar (3.2 oz / ~½ cup)
- 5g baking powder (1 tsp)
- Seeds of 1 vanilla pod or 1 tsp extract
- 1 pinch fine salt
Instructions
- Cream together sugars, vanilla, and soft cannabutter until smooth.

- Bake at 165°C / 330°F for 25–30 minutes, until edges are golden.
- Cool fully before serving.
Storage
Store cookies in an airtight container at room temperature for up to 7 days. Do not freeze dough, as this may affect THC potency distribution.
Want a Lower Dose?
Cut butter dose in half (75g infused + 75g regular) to make ~10mg cookies. Or make 32 smaller cookies instead of 16.

Cannabis Oil Ratio Calculator: Infusions Made Simple
Infusing cannabis oil is one of the most versatile ways to create edibles, tinctures, or topicals. Whether you prefer coconut oil for its binding properties or olive oil for flavor and health benefits, knowing your oil-to-cannabis ratio is the key to accurate dosing.
What is a Cannabis Oil Ratio?
The cannabis oil ratio represents how much THC (or CBD) is infused into every milliliter or gram of oil. This lets you calculate exactly how potent each drop, spoonful, or serving in your recipe will be.
Example:
- 5 grams of cannabis at 18% THC = ~900mg THC potential
- Decarbed: ~75% efficiency → 675mg active THC
- Infused into 250ml coconut oil (≈ 1 cup)
- = ~2.7mg THC per ml (or ~80mg per fl oz)
Why Choose Oil?
- Coconut oil: High fat content = great cannabinoid absorption.
- Olive oil: Subtle taste, healthy fats, perfect for savory dishes.
- MCT oil: Popular for tinctures & fast-absorbing infusions.
Use Our Calculator
Our edibles dosage calculator now supports oil infusions with both metric (ml, g) and imperial (oz, fl oz) units. It adjusts for decarboxylation efficiency and lets you estimate potency per drop, per teaspoon, or per serving.
Try it now and infuse with confidence.

Cannabis Tincture Calculator: Precision in Every Drop
A cannabis tincture (sometimes called Green Dragon) is an alcohol-based infusion that delivers cannabinoids quickly and discreetly. By understanding your tincture ratio, you can measure exactly how much THC (or CBD) is in every drop or milliliter of liquid.
What is a Cannabis Tincture Ratio?
The tincture ratio is the amount of active cannabinoids dissolved into your alcohol base. This determines potency per ml, teaspoon, or dropper (≈ 1ml).
Example:
- 7g cannabis at 20% THC = 1,400mg THC potential
- After decarb: ~1,050mg usable THC
- Infused into 100ml high-proof alcohol (e.g. 190-proof Everclear)
- = ~10.5mg THC per ml (≈ 0.5mg per drop)
Why Choose Tinctures?
- Fast absorption: Place under tongue for quicker onset.
- Discreet: Easy to dose without cooking.
- Long shelf life: Alcohol preserves cannabinoids for years.
- Versatile: Can be mixed into drinks, teas, or recipes.
Use Our Calculator
Our edible dosage calculator now includes an alcohol option so you can calculate potency per drop, per ml, or per recipe. Supports metric and imperial units, with automatic adjustments for decarboxylation efficiency.

Cannabutter vs Oil vs Tincture – Quick Comparison
Not sure whether to use butter, oil, or alcohol tincture? Here’s a side-by-side comparison to help you choose the right method for your next infusion.
| Feature | Cannabutter | Cannabis Oil | Alcohol Tincture |
|---|---|---|---|
| Best Use | Baked goods, cookies, brownies | Cooking, salad dressings, capsules | Sublingual drops, drinks, cocktails |
| Absorption Speed | Slow (digestion required) | Slow (digestion required) | Fast (sublingual ~15–30 min) |
| Shelf Life | 1–2 weeks refrigerated | Several months (if stored properly) | Years (alcohol is preservative) |
| Flavor | Rich, buttery, classic edible taste | Neutral (depends on oil used) | Strong, herbal, sometimes bitter |
| Discreet? | Low (strong smell when baking) | Medium (oil looks “normal”) | High (looks like regular tincture) |
| Difficulty | Easy – beginner friendly | Easy – just swap butter with oil | Intermediate – alcohol handling required |
Whether you want classic edibles, a healthy alternative, or a fast-acting tincture, our dosage calculator makes sure your potency is always accurate.
What is an Edible Calculator?
An edible calculator is a tool that helps you determine the precise THC and CBD dosage in your homemade cannabis edibles. Whether you're making cannabutter, infused oils, or tinctures, calculating the correct potency ensures safe and consistent dosing.
How to Calculate Edible Dosage
To calculate edible dosage accurately, you need to account for several factors:
- THC percentage in your starting material (flower, concentrate, etc.)
- Decarboxylation efficiency (oven decarb 75% in config.json—raw THCA converts to THC when heated; see decarb calculator)
- Infusion efficiency (typically 80% - not all THC transfers to the solvent)
- Total amount of cannabis used
- Total amount of butter, oil, or tincture produced
- Number of servings in your recipe
THC Per Serving & Per Batch
Our calculator automatically computes:
- Total THC per batch: The total milligrams of THC in your entire infusion
- THC per serving: How many milligrams of THC are in each individual serving
- Cannabutter ratio: The optimal ratio of cannabis to butter/oil for your desired potency
Use the calculator above to get precise calculations for your specific recipe. Simply enter your cannabis details, choose your solvent (butter, coconut oil, MCT oil, or alcohol tincture), and specify your recipe size.
