Ml to G
Converting ml to grams depends on one thing: the density of the substance. This ml to g calculator handles the math — pick an ingredient, type a milliliter value, and get the weight in grams. It works for water, milk, flour, sugar, honey, butter, and cooking oil. The ml to g formula, a conversion table, and an ingredient density table are all below.

The Formula
Milliliters to Grams Formula
The milliliters to grams formula is a single multiplication: grams = milliliters × density (g/mL). Density is the conversion factor — it tells you how many grams sit inside one milliliter of a given substance.
Water has a density of 1.00 g/mL. Honey sits at 1.42 g/mL — for honey thickness, that extra mass comes from sugars packed tight. Flour lands at just 0.53 g/mL because air fills the gaps between particles. These three numbers show why you can't swap ml and grams without knowing what you're measuring.
When you scoop 100 mL with a measuring cup, you measure volume. But a recipe that asks for grams wants weight. The ml to g formula bridges that gap. Without the density factor, 100 mL of flour and 100 mL of honey look the same — even though honey weighs nearly three times as much. A kitchen scale reads weight directly. When you only have a measuring cup, this formula is your fallback.
Volume unit
What Is a Milliliter?
A milliliter (mL) is a unit of volume in the metric system. One milliliter equals one-thousandth of a liter — or about 20 drops from a medicine dropper. A standard US measuring cup holds 236 mL. A 500 ml water bottle is roughly two cups.
Milliliters measure space, not weight. A milliliter of water and a milliliter of honey fill the same spot inside a graduated cylinder, but they land on a kitchen scale at very different readings. That's why converting from milliliters to grams always requires a density value.
In chemistry and medicine, milliliters appear on syringes, beakers, and IV bags — during pharmaceutical compounding, precise mL readings prevent dosing errors. In cooking, you'll find them on liquid ingredient labels and measuring cups. The metric system built the milliliter around water at 4°C — one mL of water at that temperature weighs exactly one gram.
Weight unit
What Is a Gram?
A gram (g) is a unit of mass in the metric system. One gram equals one-thousandth of a kilogram. A single paperclip weighs about 1 gram. A standard US nickel coin weighs 5 grams. 50 grams of flour — a common baking amount — fits in the palm of your hand.
Grams measure weight, not volume. That's the opposite of milliliters. When a baking recipe says "50 grams of sugar," it asks for a specific weight. This gives you more accurate results than scooping with a measuring cup, because weight stays consistent. 500 grams of flour is always 500 grams — sifted, spooned, or compacted.
Professional bakers, pharmacists, and chemists prefer grams over volume for cooking measurements. In a home garden, you might weigh fertilizer in grams. In medicine, dosing by grams avoids the guesswork of liquid measurements. The metric system ties everything back to the gram and kilogram as base units of mass.
100 mL of each ingredient — different weights
Common question
Is 1 mL Equal to 1 g?
Short answer: only for water. Water was the reference point when the metric system was created. One milliliter of water at room temperature weighs one gram. That's not a coincidence — it's the definition.
For every other substance, the answer changes. One mL of honey weighs about 1.42 grams because honey is denser than water — its sugars pack tighter. During yeast activation, 1 mL of the liquid mixture still sits close to water's density. But 1 mL of flour weighs about 0.53 grams because air fills the space between flour particles.
This matters in cooking and baking. If a recipe says "100 mL of sugar" and you assume that equals 100 grams, you'll add about 15 grams too much. For honey, the error jumps to 42 extra grams. The specific gravity of each ingredient decides whether 1 mL = 1 g or not. A conversion calculator removes the guesswork.
Step by step
How to Convert mL to g
The ml to gram conversion takes three steps. No special tools required — just the ml to g formula and a density value from the ingredient density table.
Pick your ingredient
Different substances have different densities. Water, milk, flour, sugar, honey, butter, and oil each carry their own density value in g/mL. The ingredient you choose sets the conversion factor for the entire calculation.
Look up the density
Find the density of your ingredient in grams per milliliter. Common values: Water = 1.00 g/mL, Milk = 1.03, Flour = 0.53, Sugar = 0.85, Honey = 1.42, Butter = 0.96, Oil = 0.92. This ml to grams calculator has these built in. For essential oil blending or pharmaceutical compounding, use the specific gravity listed on the product label.
Multiply: mL × density = grams
Take your milliliter value and multiply it by the density. Example: 250 mL of milk × 1.03 g/mL = 257.5 grams. 236 mL of flour × 0.53 g/mL = 125.08 grams. That's the volume to weight conversion — done. The conversion calculator above runs this math automatically.

Values use standard approximate densities at room temperature. Results may vary at varying temperatures, with brand differences, and by packing method for dry ingredients like flour and sugar.
Reverse conversion
How Do You Convert g to mL?
The gram to ml conversion works just like the forward one, except you divide instead of multiply. The formula: milliliters = grams ÷ density (g/mL).
Say you have 500 grams of honey and need to know how many milliliters that is. Honey's density is 1.42 g/mL. So: 500 ÷ 1.42 = 352.11 mL. For 50 grams of flour: 50 ÷ 0.53 = 94.34 mL. The density table stays the same — you just flip the operation.
This comes up when a recipe gives weight in grams but your kitchen tools measure volume. In pharmaceutical compounding, you might convert a mass reading back to a volume for dosing. During cream whipping or candle wax pouring, knowing the mL equivalent of a gram measurement helps you use the right container. Same ingredient density table, opposite operation.

Density reference
Ingredient Density Table
Every ml to g conversion depends on one number: the ingredient's density. This ingredient density table shows the values this calculator uses. They come from standard food science and kitchen references.
Density tells you how tightly packed a substance is. Honey is thick — 1.42 grams in every milliliter. For honey thickness, the high sugar content drives that number up. Flour is light and airy — just 0.53 grams per mL. Water sits right at 1.00 g/mL, the baseline for all comparisons in the metric system.
These values work well for cooking, baking, home garden measurements, and general science. For ink density checks, perfume formulation, or epoxy resin curing, check the material safety data sheet for specific gravity under your working conditions. Density shifts at varying temperatures, under pressure changes, or at high altitude labs.
FAQs
ML to Grams FAQ
Common questions about converting milliliters to grams, density values, and when 1 mL does (and doesn't) equal 1 gram.
How can I convert mL to grams?
Multiply the milliliter value by the density of the ingredient in g/mL. For water, that's simple: 100 mL × 1.00 g/mL = 100 grams. For flour, it's 100 mL × 0.53 g/mL = 53 grams. The formula is always: grams = mL × density. A kitchen scale or this ml to g calculator does the same math for you, just faster.
Is 1 mL equal to 1 gram?
Only for water. Water has a density of 1.00 g/mL, so 1 mL of water weighs exactly 1 gram. That's by design — the metric system defined the gram based on water. But milk, honey, flour, sugar, oil, and butter all have different densities. 1 mL of honey weighs about 1.42 grams, while 1 mL of flour weighs only about 0.53 grams.
