# Tabel Berat Baja: kg/m untuk Batang Bulat, Hollow, Besi Pipih, dan Pipa

Berat per meter batang bulat baja 6–100 mm, hollow persegi, besi pipih, dan pipa – dengan rumus kg/m = 0.00785 x luas dalam mm2 dan contoh perhitungan.

## Rumus berat baja: kg/m = 0.00785 x mm2

Setiap angka berat per meter di tabel ini berasal dari satu rumus: kg/m = luas penampang dalam mm2 x 0.00785. Konstanta itu adalah massa jenis baja (7,850 kg/m3) dibagi satu juta. Batang bulat 20 mm memiliki luas 314 mm2, jadi beratnya 314 x 0.00785 = 2.47 kg/m. Ingat 0.00785 dan Anda bisa memverifikasi tabel berat baja mana pun dalam hitungan detik – atau pakai [Kalkulator berat logam](https://nestingcalc.com/id/metal-weight-calculator/) untuk menghitung ukuran apa pun secara langsung.

## Tabel berat batang bulat (baja pejal)

Batang bulat pejal adalah kasus paling sederhana: luas = pi/4 x d2.

| Diameter (mm) | Luas (mm2) | kg/m |
| --- | --- | --- |
| 6 | 28 | 0.22 |
| 8 | 50 | 0.39 |
| 10 | 79 | 0.62 |
| 12 | 113 | 0.89 |
| 16 | 201 | 1.58 |
| 20 | 314 | 2.47 |
| 25 | 491 | 3.85 |
| 30 | 707 | 5.55 |
| 40 | 1,257 | 9.86 |
| 50 | 1,963 | 15.41 |
| 60 | 2,827 | 22.20 |
| 80 | 5,027 | 39.46 |
| 100 | 7,854 | 61.65 |

Besi beton mengikuti tabel yang sama – besi beton 12 mm berbobot 0.89 kg/m, jadi batang 12 m berbobot 10.7 kg.

## Tabel berat hollow persegi (SHS)

Hollow persegi mengurangi rongga dalam: luas = a2 - (a - 2t)2.

| Profil a x a x t (mm) | Luas (mm2) | kg/m |
| --- | --- | --- |
| 20 x 20 x 2 | 144 | 1.13 |
| 25 x 25 x 2 | 184 | 1.44 |
| 30 x 30 x 2.5 | 275 | 2.16 |
| 40 x 40 x 2 | 304 | 2.39 |
| 40 x 40 x 3 | 444 | 3.49 |
| 50 x 50 x 3 | 564 | 4.43 |
| 60 x 60 x 3 | 684 | 5.37 |
| 60 x 60 x 4 | 896 | 7.03 |
| 80 x 80 x 4 | 1,216 | 9.55 |
| 100 x 100 x 4 | 1,536 | 12.06 |
| 100 x 100 x 6 | 2,256 | 17.71 |

Ketebalan dinding lebih berpengaruh daripada yang duga kebanyakan orang: menggandakannya dari 2 mm ke 4 mm pada hollow 40 mm hampir menggandakan beratnya.

## Tabel berat besi pipih

Besi pipih adalah lebar x tebal x 0.00785.

| Lebar x tebal (mm) | Luas (mm2) | kg/m |
| --- | --- | --- |
| 20 x 3 | 60 | 0.47 |
| 25 x 5 | 125 | 0.98 |
| 30 x 5 | 150 | 1.18 |
| 40 x 5 | 200 | 1.57 |
| 50 x 5 | 250 | 1.96 |
| 50 x 6 | 300 | 2.36 |
| 60 x 6 | 360 | 2.83 |
| 80 x 6 | 480 | 3.77 |
| 80 x 8 | 640 | 5.02 |
| 100 x 8 | 800 | 6.28 |
| 100 x 10 | 1,000 | 7.85 |

Cek yang praktis: besi pipih 100 x 10 berbobot tepat 7.85 kg/m karena luasnya 1,000 mm2 – jembatan keledai: satu kg per 127 meter.

## Tabel berat pipa (seri medium)

Pipa mengurangi lubang dalamnya: luas = pi/4 x (OD2 - ID2).

| Ukuran nominal | OD x dinding (mm) | kg/m |
| --- | --- | --- |
| DN25 (1 in) | 33.7 x 2.6 | 2.00 |
| DN32 (1.25 in) | 42.4 x 2.6 | 2.55 |
| DN40 (1.5 in) | 48.3 x 2.6 | 2.93 |
| DN50 (2 in) | 60.3 x 2.9 | 4.10 |
| DN65 (2.5 in) | 76.1 x 3.2 | 5.75 |
| DN80 (3 in) | 88.9 x 3.2 | 6.76 |
| DN100 (4 in) | 114.3 x 3.6 | 9.83 |
| DN125 (5 in) | 139.7 x 4.0 | 13.39 |
| DN150 (6 in) | 168.3 x 4.5 | 18.18 |

Bandingkan batang bulat 50 mm (15.41 kg/m) dengan pipa DN50 (4.10 kg/m): penampang hollow jauh lebih lambat melepaskan kekuatan per berat dibanding material pejal.

## Dari kg/m ke berat dan biaya proyek

Kalikan nilai tabel dengan panjang total: rangka bengkel dari 24 m hollow 40 x 40 x 2 berbobot 24 x 2.39 = 57.4 kg. Logam lain menskalakan menurut rasio massa jenisnya – rangka yang sama dalam aluminium berbobot 57.4 x 0.344 = 19.7 kg, dalam kuningan 62.2 kg. [Kalkulator berat logam](https://nestingcalc.com/id/metal-weight-calculator/) melakukan aritmetika ini untuk profil, material, dan jumlah apa pun, dan [Rumus Berat Logam: Baja, Aluminium, Stainless per Profil](https://nestingcalc.com/id/guides/metal-weight-formula/) menjelaskan rasio massa jenis di baliknya.
