Matokeo yanakuwa bora zaidi unapochapa.
Kuhusu kifaa hiki cha kupigia hesabu
A paint calculator estimates how much paint you need from room dimensions and the number of coats. It works out the wall area as the perimeter times the wall height — 2 × (length + width) × height — optionally adds the ceiling, subtracts an allowance for each door and window, multiplies by the number of coats, adds a waste margin and divides by the paint’s coverage rate to give the litres or gallons to buy. Coverage defaults to about 10 m² per litre (350 sq ft per US gallon) but can be overridden for the specific paint.
Worked example: a 5 × 4 m room with 2.5 m walls has a wall area of 2 × (5 + 4) × 2.5 = 90 m². Subtract one door (about 1.8 m²) and one window (1.5 m²) for 86.7 m² net; two coats over 10 m²/L with 10% waste is 86.7 × 2 ÷ 10 × 1.10 ≈ 19.1 litres.
Add up to three rooms under advanced options — rooms two and three share the wall height — to estimate a whole floor at once, with a per-room breakdown. Decorators use it to buy the right number of tins and avoid a mid-job trip to the shop.
Maswali yaliyoulizwa mara nyingi
Ninahitaji rangi ya mraba kwa kila meta ngapi?
Kifuniko kimoja cha rangi ya ukutani kwa kawaida hufunika karibu lita 1032 za Marekani katika koti moja la mraba. Mashine hii ya kupigia hesabu hutwaa meta2/litu au meta 350 za mraba/gallon isipokuwa tu ukishinda habari hizo.
Ninakadiriaje rangi kwa ajili ya nyumba nzima?
Okea hizo hupima kila chumba kwa urefu na upana chini ya uchaguzi wa hali ya juu (chumba mbili na tatu zikiwa zimeinuka ukutani). Mashine za kupiga hesabu hujumlisha kila chumba kwenye ukuta, huondoa milango na madirisha wakati mmoja, kisha hutia ndani makoti na takataka kwenye meza ya kila chumba inayoonyesha kila chumba cha Bradi.
Je, nipake rangi ya ngozi mbili?
Kwa kawaida, makoti mawili hufanya rangi iwe ngumu na idumu vizuri, hasa kwa sababu ya rangi mpya au iliyo tofauti, na ndiyo sababu mashine hiyo ya kupiga hesabu haiwezi kufanya kazi mara mbili na huiongeza rangi mara mbili.
Je, kifaa hicho cha kupigia hesabu kina dari na ncha?
Inafunika kuta kwa kutoanguka na kuongeza dari ukichagua kuta za faida ndogo - ndogo + roof roof94 chini ya machaguo ya hali ya juu. Haipimiwi kwa kila mmoja, ukitia nguo za ndani kama vile rangi iliyopakwa rangi ndogo - ndogo, bali ongeza bati ndogo ikiwa unapaka rangi tofauti.
Je, ninahitaji kupima kila mlango na dirisha kwa usahihi kabisa?
Hakuna kifaa chochote cha kupigia hesabu kinachoondoa kiwango cha kila tundu, ambacho kiko karibu vya kutosha kununua rangi.
Ninunue rangi ya ziada kiasi gani kwa ajili ya waya?
Asilimia 10 ya takataka zilizomwagika, mfyonzaji na kupishana, na kuacha kiasi kidogo cha dawa za kisasa za kugusana. Kuweka bati iliyobaki, iliyobandikwa kwenye chumba, humaanisha mchezo wa rangi hususa baadaye.
API bustanini hutumia kifaa hiki cha hesabu kutoka kwenye mfumo wa sheria
Ipigie simu kifaa hiki cha kupigia hesabu kama Junse É not doot toder. Chochote unachoacha kinatumia kiwango kilekile cha mwisho ambacho ukurasa huu haujakamilika; parameta isiyojulikana ni 400, si sufuri kimya kamwe. Soma habari kamili za API docs →
