Formula, derivation and worked example

Sand and cement lose volume when mixed with water, so the dry material needed is always more than the finished volume — 54% more for concrete and about 30% more for mortar and plaster. Split the dry volume in the ratio of the mix and the sand share is what you order. Loose river sand weighs about 1,600 kg per cubic metre.

Dry volume = wet volume × 1.54 (concrete) or × 1.30 (mortar)

Sand = dry volume × sand part ÷ sum of parts

Weight = volume × 1600 kg/m³

Substitution steps

1. Dry volume
wet × 1.54
= 15.4 m³
2. Sand share
dry × 1.5/5.5
= 4.2 m³
3. Weight
volume × 1600 kg/m³
= 6,720 kg
4. Brass
volume ÷ 2.832
= 1.48 brass

Computed example results

Sand required: 4.2 m³; 148 cu ft
Sand weight: 6.72 tonne; 6,720 kg at 1600 kg/m³
In brass: 1.48 brass; 1 brass = 100 cu ft = 2.832 m³
Tractor loads: 1.5; 1 tractor ≈ 100 cu ft
Cement in the same mix: 80.6 bags
Mix ratio used: 1 : 1.5 : 3
Cost of sand: ₹7,560

Understanding the result

Read the main result together with supporting checks, assumptions, limits and intermediate values.

For a manual check, repeat the first equation, confirm the units and change one input at a time.

Assumptions and calculation scope

Wet volume of work is assumed to be entered in m³; converting from another unit before entry avoids changing the numerical meaning of the calculation.
Type of work / mix ratio is assumed to match the real case. Choosing a different available option can change the method, factor or interpretation used by this calculator.
Sand Quantity Calculator applies the displayed Dry volume = wet volume × 1.54 (concrete) or × 1.30 (mortar) relationship to the entered construction inputs. Factors that are not exposed as inputs or stated assumptions are outside this calculator's calculation scope.

Common mistakes when using Sand Quantity Calculator

Do not mix units for Wet volume of work (m³), Sand rate (₹/m³). A unit mismatch changes the input magnitude even when the typed number looks reasonable.
Do not leave Type of work / mix ratio on the default choice unless that choice matches the real scenario; the selected option can change the calculation path or factor.
Do not replace the displayed Dry volume = wet volume × 1.54 (concrete) or × 1.30 (mortar) relationship with a different convention without also changing the underlying assumptions; compare like-for-like methods when checking the result.
Do not treat Sand required = 4.2 m³ from the worked example as a universal answer. It belongs to the displayed example inputs and must be recalculated for the actual case.

When the Sand Quantity Calculator is useful

Sand Quantity Calculator is designed for cases where Wet volume of work, Type of work / mix ratio, Sand rate are known and you need Sand required, Sand weight, In brass. The page keeps the live calculator, calculation method and worked example together so the result can be checked instead of treated as a black-box number.

Use the calculator for the scope described by its inputs and notes. The displayed method is Dry volume = wet volume × 1.54 (concrete) or × 1.30 (mortar). If the real project or decision needs factors that are not represented here, treat the result as an estimate and add the missing checks separately.

Wet volume of work and Type of work / mix ratio: what changes the answer

The worked example uses Wet volume of work = 10 m³, Type of work / mix ratio = Concrete M20 (1:1.5:3), Sand rate = 1800 ₹/m³. With those values, Sand required is 4.2 m³. Changing an input should be interpreted according to that field's unit, range, option and hint rather than by the number alone.

For this calculator, the main input roles are: Wet volume of work (m³): Measured or known wet volume of work used by the calculation engine. Type of work / mix ratio: Select the option that matches the real installation or scenario. Available choices include Concrete M25 (1:1:2), Concrete M20 (1:1.5:3), Concrete M15 (1:2:4), Concrete M10 (1:3:6). Sand rate (₹/m³): Optional input; leave the supplied default only when it matches your case.

How to sanity-check a Sand Quantity Calculator result

Start by confirming the entered values and units, then compare the substituted working with the displayed formula or calculation steps. Pay particular attention to Sand required, because it is the first worked-example output shown by the live engine.

Finally, compare the result with the assumptions, warnings and related calculators on this page. A nearby calculator can be useful as a cross-check when it measures the same workflow from a different input or output direction.

Formula

Dry volume = wet volume × 1.54 (concrete) or × 1.30 (mortar)
Sand = dry volume × sand part ÷ sum of parts
Weight = volume × 1600 kg/m³

Engineering notes

Unit notes: 1 m³ = 35.315 cu ft; 1 brass = 100 cu ft = 2.832 m³; 1 tractor trolley ≈ 100 cu ft. River sand ≈ 1,600 kg/m³, M-sand ≈ 1,750 kg/m³, so 1 m³ of sand ≈ 1,600 kg and 1 brass ≈ 4.53 tonnes.

Sand required per 1 m³ of work

Dry volume factor 1.54 for concrete and 1.30 for mortar and plaster; sand density 1,600 kg/m³. Multiply each row by your work volume in m³.

Work / mix ratio	Sand (m³)	Sand (cu ft)	Sand (kg)	Sand (brass)
Concrete M25 — 1 : 1 : 2	0.385	13.6	616	0.136
Concrete M20 — 1 : 1.5 : 3	0.420	14.8	672	0.148

1 cubic metre of sand in kg

Using the loose bulk densities in this calculator, 1 m³ of river sand is about 1,600 kg and 1 m³ of M-sand is about 1,750 kg. Moisture, grading and compaction can change the delivered weight.

1 tonne of sand in CFT

At 1,600 kg/m³, 1 metric tonne of loose river sand occupies 0.625 m³ or about 22.1 CFT. At 1,750 kg/m³, 1 tonne of M-sand is about 20.2 CFT.

1 unit or 1 brass of sand

In many Indian construction quotations, 1 unit or 1 brass means 100 CFT = 2.8317 m³. Usage can vary by region, so confirm the trolley volume and the supplier's invoice unit.

Worked example

110 m³ of M20 concrete → dry volume = 10 × 1.54 = 15.4 m³.
2Sand part = 1.5 of (1 + 1.5 + 3) = 5.5 → 15.4 × 1.5/5.5 = 4.2 m³.
3Weight = 4.2 × 1600 ≈ 6.7 tonnes.

Tips

Order 5% extra for spillage and for sand left in the pit.
Wet sand bulks up to 25% — measure after it has drained or you will be short.

Frequently asked questions

How many cubic feet is one tractor of sand?

A standard tractor trolley carries about 100 cu ft (2.83 m³); a tipper carries 300–400 cu ft.

How much is 1 m³ of sand in kg?

About 1,600 kg for loose river sand and about 1,750 kg for manufactured sand. Damp sand can read 10–25% higher because of bulking.

How many CFT is 1 tonne of sand?

About 22.1 CFT for loose river sand at 1,600 kg/m³. M-sand at 1,750 kg/m³ is about 20.2 CFT per tonne.

What is 1 unit of sand?

Many Indian suppliers use 1 unit to mean 100 CFT, the same volume as 1 brass or 2.8317 m³. Confirm the local billing convention before ordering.

What is 1 brass of sand?

One brass is 100 cubic feet, i.e. 2.832 m³. That is roughly 4.53 tonnes of river sand, or about one full tractor trolley.

Why multiply by 1.54?

Dry cement, sand and aggregate have voids. When water is added the mix compacts, so you need about 54% more loose material than the finished concrete volume.

Can I use M-sand?

Yes. Quantities are the same; manufactured sand is slightly heavier at about 1,750 kg/m³.

What inputs does the Sand Quantity Calculator use?

It uses Wet volume of work, Type of work / mix ratio, and Sand rate. Follow the unit printed for each field and choose any selectable option to match the real scenario.
