### Quick mL to oz Conversion Chart

Common milliliter values converted to U.S. fluid ounces for candle jar and packaging discussions.

| Milliliters (mL) | Ounces (fl oz) |
| --- | --- |

### Common Candle Jar Diameter: mm to inch

Bright Glassware-specific sourcing reference for jar openings, label space and wick-testing dimensions.

| Millimeters (mm) | Inches (in) |
| --- | --- |
| 60 mm | 2.36 in |
| 70 mm | 2.76 in |
| 75 mm | 2.95 in |
| 80 mm | 3.15 in |
| 85 mm | 3.35 in |
| 90 mm | 3.54 in |
| 100 mm | 3.94 in |

### Common Candle Jar Diameter: inch to mm

Useful when a buyer brief gives jar diameter or opening size in inches and the supplier drawing uses millimeters.

| Inches (in) | Millimeters (mm) |
| --- | --- |
| 1/16 in | 1.59 mm |
| 1/8 in | 3.18 mm |
| 1/4 in | 6.35 mm |
| 1/2 in | 12.70 mm |
| 1.00 in | 25.40 mm |
| 2.00 in | 50.80 mm |
| 2.25 in | 57.15 mm |

| 3.50 in | 88.90 mm |
| 3.75 in | 95.25 mm |
| 4.00 in | 101.60 mm |

Unit note: These volume charts use U.S. fluid ounces (fl oz), not ounces by weight. For wax or fragrance weight conversions, use the Unit & Capacity Calculator and the relevant mass units.

Calculator Reference

## Fragrance, Unit & Wick Reference Guides

Use these static references alongside the interactive tools so common planning values stay easy to scan, compare and share during candle jar sourcing.

### Candle Fragrance Load Examples

Examples use fragrance weight ÷ wax weight, matching the Fragrance Load Calculator above.

| Wax Weight | 6% Load | 8% Load | 10% Load | 12% Load |
| --- | --- | --- | --- | --- |
| 100 g | 6 g | 8 g | 10 g | 12 g |
| 150 g | 9 g | 12 g | 15 g | 18 g |
| 180 g | 10.8 g | 14.4 g | 18 g | 21.6 g |
| 200 g | 12 g | 16 g | 20 g | 24 g |
| 250 g | 15 g | 20 g | 25 g | 30 g |

Planning note: These are calculation examples only, not recommended fragrance levels. Always follow the maximum fragrance-load limits specified by your wax and fragrance suppliers and verify the finished candle through testing.

### Common Units in Candle Jar Sourcing

Use the Unit & Capacity Calculator when a buyer brief and supplier drawing use different measurement systems.

| Buyer Specification | Supplier Specification | Common Use |
| --- | --- | --- |
| fl oz | mL | Jar liquid capacity |
| oz | g | Wax and fragrance weight |
| inch | mm | Jar diameter, height and opening |
| lb | kg | Batch material and shipping weight |

Sourcing note: U.S. candle briefs often use fl oz, oz and inches, while supplier specifications commonly use mL, g and mm. Keep volume and weight as separate measurement types unless a verified density is available.

### Candle Jar Diameter & Wick Testing Reference

This table mirrors the testing logic in the Wick Starting Point Calculator and is intended only as a practical test-planning framework.

| Inner Jar Diameter | Practical Testing Starting Point |
| --- | --- |
| Under 25 mm / under 1 in | Use the smallest wick families and test micro-vessel behavior carefully. |
| 25 to under 51 mm / 1–2 in | Start with narrow single-wick tests and compare adjacent family sizes. |
| 51 to under 76 mm / 2–3 in | Single-wick testing is still primary, but compare multiple wick families. |
| 76 to under 102 mm / 3–4 in | Compare stronger single-wick options and, if needed, early double-wick tests. |
| 102 mm and above / 4 in+ | Plan a broad test matrix including larger families and multi-wick layouts. |

Testing note: This is not a wick-size recommendation. Final wick selection depends on the actual jar, wax, fragrance load, dye, wick construction, spacing and controlled burn-test results.

### HTP Wick Rate Chart / HTP 灯芯指标表

Reference performance metrics for HTP wick families. Use this chart with the Wick Starting Point Calculator and confirm all final wick choices through controlled burn testing.

Note / 注意： Suggested Glass Container Inner Diameter is for reference only. Final wick selection must be confirmed by proper burn testing based on the specific wax, fragrance load, additives and container configuration.

Practical Workflow

## When & How to Use These Candle Calculators

Use each tool at the sourcing or production step where a jar dimension, formula assumption or unit mismatch could affect the next decision.

01

### Select a Candle Jar

Enter the jar capacity or inner diameter, then compare the usable fill and dimensions before ordering samples.

02

### Plan Wax & Fragrance

Use the wax-fill and fragrance tools to estimate per-candle requirements and production quantities for the planned batch.

03

### Review Supplier Specs

Convert mL, fl oz, mm, inch, g and oz when buyer briefs and supplier drawings use different measurement systems.

04

### Verify Before Production

Use the wick result as a starting point, then confirm fill, component fit and burn performance with production-style samples.

## Jar Sizing & Batch Planning Basics

Two principles prevent many common sourcing and production mistakes.

### Jar Capacity Is Not Wax Weight

An [8 oz candle jar](https://brightglassware.com/sizes/8oz-candle-jars/) does not automatically hold 8 oz of wax by weight. Actual fill depends on internal volume, usable fill line, wax density, fragrance load and jar geometry.

If your finished candle uses a closure, match the jar opening and rim with compatible [candle jar lids](https://brightglassware.com/closures-accessories/candle-jar-lids/) before approving the final packaging.

- Use liquid capacity for the jar.

- Apply a realistic usable fill line.

- Use supplier-specific wax data when available.

### Planning Candle Production Batches

Batch calculations become increasingly useful at 100, 500, 1,000 and 5,000 candles, where small per-candle errors can become significant material differences.

- Include a realistic production allowance.

- Plan wax and fragrance separately.

- Confirm packaging quantity and jar supply before production.

Production Risk Control

## Why Accurate Candle Jar Planning Matters

Small assumptions at the jar-selection stage can become larger material, compatibility and sourcing problems in production.

01

Correct FillAvoid overfilling or underfilling.

02

Batch AccuracyReduce wax and fragrance variance.

03

Jar + Wick FitPlan testing around real inner diameter.

04

Clear SpecificationsAlign buyer and supplier units.

## Frequently Asked Questions

Practical answers for candle jar sizing, wax fill and production planning.

There is no single universal wax weight for every 8 oz jar. Start with the jar's actual liquid capacity, choose a usable fill percentage, then apply the planning density for your wax and your fragrance formula. The Wax & Jar Fill Calculator above performs those steps separately.

No. Fluid ounces describe volume, while ounces of wax are weight. The relationship depends on wax density, fragrance load and your chosen fill line.

Calculate the required wax for one candle, multiply by 100, then add a realistic production allowance for material retained in equipment and normal process losses.

Use the limits and recommendations from your wax and fragrance suppliers. This page calculates fragrance load as fragrance weight divided by wax weight and is intended for production planning, not as a substitute for supplier specifications.

Usable fill capacity is the working volume you plan to fill, below the container's maximum overflow capacity. It should leave appropriate headspace and be verified with the actual jar, wick, wax and lid combination.

Yes, as a planning tool. The included densities are editable planning coefficients. For production, replace them with your wax supplier's documented density or your own measured value.

The math is deterministic, but the result depends on the accuracy of your inputs. Actual fill weight can vary with wax formulation, fragrance, processing conditions and jar geometry, so physical verification is still required.

Jar inner diameter is an important starting parameter, but wick choice also depends on wax, fragrance, dye and wick construction. Use the Wick Starting Point tool to plan a test approach, then confirm with controlled burn tests.

Planning disclaimer: Calculator results are estimates for planning purposes. Actual fill weight and candle performance can vary by wax formulation, fragrance load, jar geometry, wick, dye, processing temperature and manufacturing method. Always confirm final specifications through physical filling and burn testing before production.

 `).join('')}

Starting point only. Final wick selection must be confirmed by controlled burn testing with your actual jar, wax, fragrance load, additives and fill level.
