- Wax Type: Select soy, paraffin, or beeswax, depending on your preference.
- Fragrance Load (%): We recommend 6% to 8% fragrance oil for Indian climates for the best scent and performance.
- Instant Calculation: The calculator shows your wax and fragrance oil amounts in grams instantly—no clicking needed.
Farida’s Tip
If your container doesn’t list volume, I fill it with water and pour that into a measuring cup to find out ml. It’s a handy trick when testing new jars or shapes.
Choosing the Right Wax for Indian Conditions
Not all waxes behave the same in India’s heat and humidity. Here are popular options:
- Soy Wax
My go-to wax—plant-based, clean-burning, and great scent throw when cured properly. Perfect for candles and wax sachets that resist melting in warm weather. - Paraffin Wax
Reliable with excellent scent throw, best for container candles needing strong fragrance. - Beeswax
Burns longer and cleaner with a subtle scent. Great for pillar candles and slow-release sachets.
How Much Fragrance Oil Should You Add?
The right fragrance load is key to good scent without issues.
In hot, humid India, I recommend 6%–8% fragrance oil. More than 10% can cause sweating, cracking, or wick problems.
Farida’s Tip: Always test new fragrance oils in small batches. Some scents need longer curing to shine, especially with soy wax.
Common Candle Measurement Questions
- How do I know how much wax I need for my candle jars?
Measure your jar’s volume in millilitres (ml), enter it in the calculator, and it will instantly convert it to the exact grams of wax you need.
- How do I measure fragrance oil for candles?
Fragrance oil should be measured in grams, not millilitres, because oils have different densities. The calculator automatically tells you how many grams to use based on your fragrance load.
- What’s the best fragrance load for candles in India’s climate?
For most soy, paraffin, and beeswax candles, 6%–8% fragrance load works well in India’s heat and humidity. Above 10% can cause sweating, cracking, or wick issues.
- Can I use this calculator for wax sachets and melts?
Yes! Enter the volume per sachet or melt, choose your wax type, and fragrance load. The calculator adjusts for any number of sachets.
- How do I measure my container’s volume if it’s not listed?
Fill the container with water, pour into a measuring cup, and note the ml. That’s your volume for the calculator.
- Which wax is best for hot and humid areas?
Soy Wax: Clean burning, plant-based, great for sachets and candles.
Paraffin Wax: Strong scent throw, ideal for container candles.
Beeswax: Long burn time, subtle scent, perfect for pillars and sachets. - Do I need to cure candles before using them?
Yes. Soy candles need 7–14 days cure time. Paraffin cures faster, and beeswax benefits from at least a week.
- Why does the calculator use grams instead of ml for results?
Grams are more accurate because wax and fragrance oil have different densities, ensuring consistent results.
- Can this tool help reduce waste?
Yes. Exact measurements mean no overpouring wax or using too much fragrance oil, saving you money and resources.
- Can beginners use this calculator?
Yes. It’s simple for first-time makers and accurate for small businesses.
Beginner Mistakes to Avoid
After years of trial and error, here are mistakes I see often:
- Pouring without measuring
- Skipping fragrance oil calculations
- Measuring fragrance oil in ml, not grams
- Pouring at wrong temperatures
- Not curing long enough
Farida’s Tip: Keep a candle journal. Log wax type, wick size, fragrance %, and temperatures. It helps fix problems faster and avoid repeating mistakes.
From My Table to Yours
Back when I started Candle Kin, I scribbled formulas and manually converted ml to grams—slow and messy! This calculator is made for candle lovers like us who want quick, accurate results without the math.
