Milligram Scales for Concentrates: Precision Weighing Guide
Concentrates require precision that standard scales can't provide. When a typical dab is 0.025-0.05 grams, a scale that only reads to 0.1g is essentially useless. This guide explains why milligram scales matter and how to use them effectively.
Quick Answer
Milligram scales (0.001g accuracy) are essential for concentrates. Standard pocket scales (0.1g) can't measure typical dab sizes. Key features: 0.001g readability, windshield for stability, 10-20g capacity, included calibration weights. Top picks: Smart Weigh GEM20 or AWS Gemini-20. Budget $20-35 for quality.
Why Milligram Scales Matter
For precision instrumentation and laboratory scales, Mettler Toledo provides industry-leading measurement technology.
The Math Problem
Standard dab size: 0.025-0.05g (25-50mg)
Pocket scale accuracy: 0.1g (100mg)
The problem: A 0.1g scale can't even detect a typical dab. It might show "0.0" or round incorrectly.
Real-World Impact
With 0.1g scale:
- Small dab: Shows 0.0g (undetectable)
- Medium dab: Shows 0.0g or 0.1g (inaccurate)
- Large dab: Shows 0.1g (could be 0.05-0.14g)
With 0.001g scale:
- Small dab: Shows 0.025g (accurate)
- Medium dab: Shows 0.050g (accurate)
- Large dab: Shows 0.100g (accurate)
When You Need Milligram Precision
Essential for:
- Portioning dabs consistently
- Making edibles with concentrates
- Measuring distillate/RSO
- Tracking usage accurately
- Verifying concentrate purchases
Milligram Scale Features
Must-Have Features
0.001g (1mg) accuracy:
The defining feature. Anything less can't measure typical concentrate amounts.
Windshield/draft cover:
Milligram scales are extremely sensitive. Air currents affect readings. The windshield blocks drafts.
Calibration weights included:
Frequent calibration is important at this precision. Built-in weights make this easy.
Stable platform:
Should sit firmly without wobbling. Internal stabilization helps.
10-20g capacity:
Enough for concentrate amounts while maintaining precision.
Nice-to-Have Features
- Tare function
- Multiple units (g, mg, oz, ct)
- Backlit display
- USB rechargeable
- Carrying case

Using Milligram Scales
Setup for Accuracy
Location:
- Flat, stable, hard surface
- Away from air vents/fans
- Away from windows/doors
- Room temperature environment
Preparation:
- Turn on, let warm up 30 seconds
- Close windshield
- Calibrate before important measurements
Weighing Concentrates
Step 1: Prepare
- Place scale on stable surface
- Turn on, let stabilize
- Close windshield
Step 2: Tare container
- Place silicone container or parchment on platform
- Press tare to zero
Step 3: Add concentrate
- Use dab tool to place concentrate
- Close windshield
- Wait for reading to stabilize
Step 4: Record
- Note the weight
- Display should show three decimal places (0.025g)
Tips for Accuracy
Handle carefully:
- Don't breathe on scale
- Use dab tool, not fingers
- Move slowly around scale
- Let readings stabilize
Environmental control:
- Keep windshield closed during readings
- Avoid temperature extremes
- No drafts or vibrations
Calibrate frequently:
- Before each session (for critical measurements)
- At least weekly
- After moving scale
- After temperature changes
Portioning Dabs
Standard Dab Sizes
Calculating THC
Formula:
Dab weight (g) × THC % = THC consumed
Example:
0.05g dab × 80% THC = 0.04g = 40mg THC
For context:
- Standard edible dose: 5-10mg THC
- 40mg dab = 4-8 edible servings worth
- Concentrates are potent—measure carefully
Pre-Portioning
For consistent sessions:
1. Weigh total concentrate
2. Divide by desired dab size
3. Pre-portion onto parchment
4. Each portion ready to use
Benefits:
- Consistent experience
- Track usage accurately
- No over-consuming
- Know exactly what you're taking
Making Edibles with Concentrates
Why Precision Matters
The stakes:
- 10mg difference = significantly different experience
- Under-dosing = ineffective
- Over-dosing = uncomfortable
Dosing Calculation
Step 1: Know your concentrate potency
Check lab results. Example: 80% THC distillate.
Step 2: Calculate THC per serving
If you want 10mg THC per serving:
- 10mg ÷ 0.80 = 12.5mg concentrate needed
- 0.0125g per serving
Step 3: Multiply by servings
10 servings × 0.0125g = 0.125g total concentrate needed.
Step 4: Weigh precisely
Milligram scale shows 0.125g—perfect accuracy.
Common Edible Mistakes
Avoided with milligram scale:
- Eyeballing concentrate amount
- Inconsistent portion sizes
- Not accounting for potency variation
- Under/over dosing entire batch
Maintenance and Care
Keeping Accuracy
Regular calibration:
Essential at milligram precision. Use included weights.
Clean carefully:
- Wipe platform with dry cloth
- Don't use liquids
- Clean after concentrate contact
Proper storage:
- Keep in case when not in use
- Protect from dust
- Avoid humidity
- Room temperature
Battery Considerations
For consistent accuracy:
- Replace/charge batteries regularly
- Low battery = inaccurate readings
- Some scales warn when batteries low
Troubleshooting
Inconsistent Readings
Causes:
- Air currents (close windshield)
- Unstable surface
- Low battery
- Needs calibration
Can't Get Zero
Causes:
- Something on platform
- Needs calibration
- Draft affecting scale
- Warm-up period needed
Reading Drifts
Causes:
- Temperature changing
- Concentrate is sticky (weight shifting)
- Needs calibration
- Scale malfunction
Summary
Milligram scales are non-negotiable for concentrates:
- 0.001g accuracy is essential
- Windshield blocks air currents
- Calibrate frequently for precision
- Smart Weigh GEM20 is best value
- Spend $20-35 for quality
The difference between a milligram scale and pocket scale for concentrates is like using a ruler versus a measuring tape for millimeters—one works, one doesn't.

Frequently Asked Questions
Standard pocket scales (0.1g accuracy) can't measure typical dab sizes accurately. A 0.1g dab is on the edge of detection, and smaller portions won't register. Milligram scales (0.001g) can measure 0.025g dabs precisely.
