Tola, Millilitre and Gram: How Oud Is Sold and Priced

One seller quotes a tola, another quotes millilitres, a third quotes grams. The numbers look comparable and they are not. Here is how to put them on the same footing.

Sep 25, 2026

Ask three sellers the price of tola oud oil and you will get three answers that cannot be compared. One quotes a tola. One quotes millilitres. One quotes grams per vial. The figures sit next to each other looking like currency conversions.

Most oud guides skip straight to origins and notes. That leaves you holding a 12ml bottle, a half tola and a 3 gram decant, with no way to tell which one is actually the better buy. The unit is doing quiet work inside the price, and in a material this expensive the unit is where the money hides.

By the end of this you will know what a tola weighs, why oud is sold by mass rather than by volume, and how to reduce any two quotes to the same number before you spend anything.

What a Tola Actually Is

The tola is a unit of mass from the Indian subcontinent, used first for weighing gold and silver. One tola is 11.6638 grams. It travelled outward from South Asia into the Gulf along the same routes that carried attar, and it stayed in the fragrance trade long after most of the world went metric.

Here is where it goes wrong. A tola measures weight. A bottle measures volume. The traditional full tola flacon holds roughly 12ml, and that figure is a convention rather than a conversion. Twelve millilitres of a light floral oil and twelve millilitres of a dense oud blend do not weigh the same amount, so the same bottle can hold noticeably different quantities of material.

The formats you will actually be quoted:

Full tola. Around 12ml in the traditional flacon. The default retail size across the Gulf and South Asia.
Half tola. Around 6ml. Common for single origin oils where a full tola would be a serious outlay.
Quarter tola. Around 3ml. Often the smallest quantity a seller will decant for you.
Gram. How good oud oil is quoted at the top of the market, because weight leaves nothing to interpret.
Millilitre. How Canadian retail quotes almost everything, oils included.
The tola bottle itself. Ornate glass sized to hold about one tola, sold empty as often as filled. The bottle is packaging, not evidence.

Why the Unit Changes the Price

Density Is Not a Rounding Error

Oud oil is dense and viscous. Quote one oil by volume and by weight and the two figures drift apart. Across a full tola that drift is real money. It also tends to favour whoever picked the unit, which is worth remembering when a seller volunteers one and resists the other.

Dilution Hides Inside Volume

Oil cut with a carrier fills a bottle exactly as well as uncut oil does. A 12ml bottle tells you how much liquid you received and nothing whatsoever about concentration. Weight plus a stated concentration tells you considerably more. When a price looks low for the size, carrier oil is usually the explanation, and why oud is expensive sets out what the floor price for real material looks like.

Small Sizes Cost More Per Gram

Decanting is labour, and small bottles cost more per unit than large ones. A quarter tola will almost always work out dearer per gram than a full tola. That is ordinary trade practice rather than a markup to argue over. It is also why samples are the cheapest way to learn what you like and the most expensive way to build a collection.

The Same Oud, Quoted Four Ways

Unit	What it measures	Typical size	What to watch
Tola	Mass, 11.6638 g	Full, half, quarter	Bottle volume is convention, not arithmetic
Gram	Mass	1 g to 12 g	The clearest basis for comparing two oils
Millilitre	Volume	3ml, 6ml, 12ml	Silent on density and on dilution
Tola flacon	Nothing, it is a container	About 12ml	Ornate glass proves nothing about contents

Convert every quote to grams before you compare anything. If a seller cannot or will not tell you the fill weight, you have not been given enough information to judge the price.

What This Means for a Toronto Buyer

Walk into a fragrance counter almost anywhere in the GTA and you will be quoted millilitres. Ask at a shop stocking imported Gulf or South Asian stock and you may well be quoted tolas instead. Both conventions are normal here, often within a few blocks of each other, which is why Toronto buyers run into this confusion more than most.

We bottle by hand in Toronto and state the fill by weight as well as by volume, so nothing needs reverse engineering. One local detail worth knowing. Oil contracts slightly in the cold, so a bottle carried home across the city in February can look marginally fuller once it reaches room temperature. Nothing was added. The oil simply expanded again.

Frequently Asked Questions

How many grams is a tola? One tola is 11.6638 grams. Most sellers round it to 11.66, or just say twelve. That is fine in conversation and not fine on a large purchase.

Is a tola the same as 12ml? No. A tola is a weight and 12ml is a volume. The traditional full tola bottle holds roughly 12ml, so the two line up by custom rather than by calculation.

Should I buy by gram or by millilitre? By gram wherever the seller allows it. Weight is unambiguous. Volume tells you how much space the liquid occupies and nothing about what is dissolved in it.

Why does a quarter tola cost more per gram? Decanting takes time and small bottles cost more per unit to buy and fill. Paying a premium for a small format is standard in this trade.

Does a heavier bottle mean better oud? No. Glass weight varies enormously between flacons. Ask for the fill weight rather than the gross weight, and weigh the oil rather than the packaging.

Can I convert millilitres to grams myself? Only with the oil's density, which most sellers do not publish. Ask for the weight directly instead of trying to calculate it.

Hand-Bottled in Toronto

We keep one attar and we keep it honest. Alcohol free, oud blended with musk, sandalwood and amber, bottled by hand here rather than filled offshore and relabelled. Every bottle leaves with its fill weight stated, because a buyer spending this much on oil deserves to know what is in the glass rather than how tall the glass is. Deliveries run on weekdays across Toronto, Peel, York, Halton and Durham, driven by us. Join the launch list for the first batch.
