| Dia (mm) | 8 | 10 | 12 | 16 | 20 | 25 | 32 |
|---|---|---|---|---|---|---|---|
| Weight per running meter (kg) | 0.395 | 0.617 | 0.888 | 1.579 | 2.469 | 3.858 | 6.313 |
Standard thumb-rule formula: weight (kg/m) = D² ÷ 162, where D is diameter in mm.
Why these conversions come up on every site
India's land and property market runs on square feet, but drawings, IS codes and most engineering references use the metric SI system — meters, square meters, cubic meters. Every contractor, site engineer and billing clerk ends up converting between the two constantly: a client quotes a plot in square feet, the structural drawing gives spans in meters, and the BOQ needs quantities in cubic meters for RA billing. Keeping these conversions accurate matters because a small unit error compounds fast — a 2% area miscalculation on a large slab is real money.

From measurement to bill — the next step
Converting units by hand is fine for a one-off check. But when you're measuring dozens of items across a site every week, tracking them against a BOQ, and turning them into RA bills with retention and GST — that's where a calculator stops being enough. True Site Sync records measurements directly in the units your BOQ uses, computes quantities automatically, and carries them straight through to billing.
Frequently asked questions
How do you convert square feet to square meters?
Multiply by 0.092903. Example: 1000 sq ft × 0.092903 = 92.9 sq m.
How do you convert feet to meters?
Multiply by 0.3048. Example: 10 ft × 0.3048 = 3.048 m.
How many cement bags per cubic meter of concrete?
For a common M20 mix (1:1.5:3), roughly 8 bags (50 kg each) per m³, using the standard dry-volume method. Use the calculator above for other ratios.
What is the formula for steel rebar weight?
Weight (kg/m) = D² ÷ 162, where D is the bar diameter in mm. Multiply by length in meters for total weight.
How many square feet in a square meter?
1 square metre ≈ 10.7639 square feet.
