The calculator shows you need 0.737g of CBD isolate, 0.167g of CBG distillate, 0.109g of Delta-8 distillate, and 0.05g of terpenes for a 1g batch. Perfect precision every time.
⚠️ Safety Note: The Vape Calculator includes important safety warnings—it will never let you add MCT oil or other dangerous additives to vape products. Only use ingredients specifically designed for inhalation.
3. 0.3% Delta-9 THC Limit Calculator
🔗 Try the THC Limit Calculator →
Ensure your hemp products meet federal compliance standards with instant Delta-9 THC verification.
Staying compliant with the 2018 Farm Bill’s 0.3% Delta-9 THC limit is crucial for any hemp business. Our THC Limit Calculator makes compliance checking quick and easy, whether you’re testing a single product or verifying an entire product line.
Key Features:
- Instant Compliance Verification: Know immediately if your product meets federal hemp standards
- Weight & Volume Support: Works with grams, mg, oz, lb, kg, ml, and fl-oz
- Reference Table: See maximum allowable Delta-9 THC at common concentration levels (0.05% to 0.3%)
- Liquid Conversions: Automatically handles MCT oil density for tinctures and liquids
Perfect For:
- Verifying products before lab testing to avoid costly failures
- Formulating products with Delta-9 THC while staying compliant
- Quality control checks during production
- Understanding how much Delta-9 THC different concentrations represent
Real-World Example:
You’re creating a 30ml tincture and want to know the maximum Delta-9 THC you can include. Enter “30ml” and the calculator instantly tells you that at 0.3%, you can have up to 8.28mg of Delta-9 THC. The reference table also shows what you’d get at 0.1% (2.76mg), 0.2% (5.52mg), etc. This helps you formulate confidently within legal limits.

Best Practices for Using the Calculators
To get the most out of these tools, keep these formulation best practices in mind:
Equipment Matters
Invest in a precision scale that measures to at least 0.01g (10mg). For smaller batches, consider a milligram scale (0.001g). The calculators give you precise measurements—make sure you can measure them accurately!
Source Material Quality
Know your source material purity. Request Certificates of Analysis (COAs) from your cannabinoid suppliers. The more accurate your purity input, the more accurate your final product.
Start Small, Scale Up
When developing new formulations, start with the smallest batch size. Test it, refine it, then scale up production. The calculators make scaling easy—just change the batch size.
Document Everything
Take screenshots of your calculations or write down your recipes. While the calculators don’t save data, maintaining your own formulation library is essential for consistency and quality control.
Test Your Products
For commercial products, always conduct third-party lab testing. Our calculators help you formulate accurately, but lab verification ensures compliance and builds customer trust.
Real-World Applications

“I love that I can check THC compliance before sending products for testing. It’s saved me from costly lab test failures and given me confidence in my formulations.”
The Science Behind the Calculators
For those interested in the technical details, here’s what makes these calculators accurate:
Purity Compensation
When you enter a purity percentage (e.g., 95% CBD isolate), the calculator uses this formula:
Actual Weight Needed = Target Amount / (Purity / 100)
So if you need 1000mg of pure CBD and your isolate is 95% pure, you need 1000 / 0.95 = 1052.6mg of isolate.
Density Calculations
For liquid volumes (like tinctures), we use MCT oil’s density of approximately 0.92 g/mL. This means 1 mL of MCT oil weighs 0.92 grams, allowing accurate weight-to-volume conversions.
Percentage Validation
The Vape Calculator validates that your total cannabinoid and terpene percentages equal 100%. This ensures you’re not over or under-formulating and helps prevent common mistakes.
Future Updates & Features
We’re committed to continuously improving these tools based on community feedback. Here’s what we’re considering for future updates:
- Edibles calculator with dosing per serving
- Topicals formulation tool
- Cost calculator for pricing your products
- Batch scaling and conversion tools
