Understanding Margin of Error

What ยฑ Means

When specs say "ยฑ0.1g":

  • Reading of 5.0g means actual could be 4.9-5.1g
  • Reading of 3.5g means actual could be 3.4-3.6g

Error Compounds with Small Weights

At larger weights:

5.0g ยฑ 0.1g = 2% potential error

At smaller weights:

0.5g ยฑ 0.1g = 20% potential error

Lesson: Accuracy matters more for smaller amounts.

Why Cheap Scales Are Worse

Better scales:

  • Tighter actual accuracy than spec
  • More consistent
  • Better at edges of range

Cheap scales:

  • May not meet stated spec
  • Worse at small weights
  • More environmental sensitivity


Testing Your Scale's Accuracy

Using Known Weights

Calibration weights (best):

  • Known precise weight
  • Use to verify and calibrate

Coins (adequate):

  • US nickel = 5.00g
  • US penny (post-1982) = 2.50g
  • Stack for larger weights

Precision Test

1. Weigh same item 5 times

2. Record each reading

3. All same = good precision

4. Variation = precision issue

Accuracy Test

1. Weigh known weight (calibration weight or coins)

2. Compare to known value

3. Close = good accuracy

4. Off = needs calibration or replacement


Improving Your Readings

Environmental Factors

For best accuracy:

  • Level, stable surface
  • Away from air currents
  • Consistent temperature
  • No vibrations

Usage Factors

For best accuracy:

  • Calibrate regularly
  • Fresh batteries
  • Let scale warm up
  • Don't rush readings

Scale Factors

For best accuracy:

  • Quality brand
  • Appropriate accuracy for task
  • Proper maintenance
  • Not exceeding capacity


Quick Reference

Accuracy by Scale Type

Scale TypeTypical AccuracyBest For
Kitchen scale1gLarge amounts only
Pocket scale0.1gFlower, general use
Precision pocket0.01gSmall amounts, better flower
Milligram scale0.001gConcentrates, precision

When Readings Matter Most

  • Verifying purchases: Need accuracy
  • Consistent dosing: Need precision
  • Making edibles: Need both
  • Casual use: Either works


Summary

Understanding scale specs helps you:

1. Choose right accuracy for your needs

2. Interpret readings correctly

3. Identify problems when they occur

4. Not overpay for unnecessary precision

For most cannabis flower use, 0.1g accuracy is sufficient. For concentrates or precision work, 0.001g is essential. Don't be fooled by extra decimal placesโ€”readability isn't the same as accuracy.
